SYSTEM OF SYMBOLS FOR ANTIFRICTION BEARINGS*
GENERAL
1. The system of numbering bearings is designed for: a) marking bearings
during their production, b) indicating requirements of drawings and specifications,
c) use in documents concerning orders and shipments as well as for accounting and
stock inventory and d) use as reference in technical literature.
2. The symbol identifies the principal characteristics of the bearing including:
a) Bore of bearing or bushing,
b) Series of bearing,
c) Type of bearing,
d) Design features of the bearing,
e) Bearing accuracy.
All the digits of the bearing number, which identify the above characteristics
are comprised of numerals except for the bearing accuracy. The latter is indicated
by a letter arranged at the left of the numerical designation.
3. The characteristics indicated by the separate digits, in accordance with their
order in the bearing number, are given in Table 1. .

DESIGNATION OF THE BORE OF THE BEARINGS
4. The bore. of the bearing (or shaft diameter), for dimensions less than ;
495 mm, is designated in the bearing number by the first two digits from the right
which is the quotient obtained when the bearing bore is divided by 5. If the bore
cannot be divided by 5 without a remainder, the whole number part of the
quotient is indicated and the numeral "9" is placed in the third place.
This rule ha the following exceptions:
a) For all bearings with bores from 10 to 20 mm, except magneto (separable)
bearings, the bearing bore is designated in accordance with Table 2.
Table 2

03
If the bearing bore does not coincide with the standard diameters indicated
in Table 2, the bearing is designated in accordance with the nearest standard bore
and the digit "9" is placed in the 3rd place.
b) For all bearings having a bore up to 9 mm inclusively, the first digit of the
number
?
number indicates the actual bore in millimeters and the digit "0" is placed in the
3rd place. The second digit, in this case, -indicates the series of the bearing (see
lower, paragraph 6).
Example : 1.025 indicates a double row self-aligning light series ball
bearing with a ? bore of 5 mm; 25 indicates a single row light series ball bearing
with a bore of 5 mm. If the bearing bore is not a whole number the bore designation
is taken as the nearest whole number. In this case "0" is retained in the 3rd place
and the digits "4" or "5" are placed in the 2nd place.
Example : Single row ball bearings with bores of 1/4" (6.35 mm) and /16"5
(7.938 mm) may. be designated as 46 and 58.
c) For magneto (separable) ball bearings (series 6000) the first two digits of the
bearing number indicate the actual bore of the bearing.
Example : 6017 indicates a magneto ball bearing with a bore of 17 mm.
10? STANKOIMPORT
5. Bearings having a bore of 495 mm or more are designated by a fraction.
The denominator of this fraction indicates the actual bore while the numerator
contains digits identifying the other characteristics of the bearing in accordance
with Table 1 and in the order stipulated for all bearings.
DESIGNATION OF THE SERIES OF THE BEARINGS
6. The third digit, together with the 7th digit identifies the series of bearings
of all bores, except small bores (up to 9 mm inclusively), in accordance with
Table 3. Zeroes to the left of the last significant digit (reading from right to left)
are omitted.
7. The series of bearings having bores up to 9 mm (inclusively) are designated
by the digits "1", "2", "3", "6", "7", "8" or "9" in the second place corresponding
to the designation of the series of bores in accordance with Table 3. In this case,
the digit "6" as well as the digit "7" indicates an indefinite (non-standard) series.
Example : 37 indicates a single row medium series ball bearing with a bore
of 7 mm; 68 indicates a single row non-standard series ball bearing with a bore
of 8 mm.

CHARACTERISTICS OF MAIN
TYPES OF ANTIFRICTION BEARINGS
1. SINGLE ROW BALL BEARINGS
Fig. 6
Single row ball bearings, due to their
design features, are capable of carrying a
thrust load, acting in either direction along the
axis of the shaft, besides the usual radial load.
This thrust load, however, should not exceed
70 per cent of the non-utilized permissible
radial load at a given computed average life.
If the radial clearance between the balls
and races of the bearing rings is increased,
these bearings acquire the properties of radial-
thrust bearings and provide excellent perfor-
mance in carrying pure thrust loads. In this
capacity, they often are substituted for ball
thrust bearings.
The capacity for carrying thrust loads in
either direction allows this type of bearing to
be used for fixing shafts or housings in an
axial direction.
Single row ball bearings are capable of operating at higher speeds than other
alternative designs of bearings of the corresponding size.
The maximum allowable operating speed of single row radial bearings may
be increased if the bearings are more accurately manufactured as well as with
the use of solid retainers of antifriction materials such as textolite, brass,
duralumin, etc.
Single row ball bearings have the lowest friction losses in comparison with
other types of bearings of the corresponding size. For this reason, this type of
bearings should be given preference in designing machinery if its computed
average life is within the limits which provide a normal working capacity of
the machine.
Single row ball bearings provide satisfactory performance in cases in which
the housings of all bearings, mounted on one shaft, are bored in a single set-up or
measures are taken to ensure that the bores are in accurate alignment. It is necessary
to remember that this design of bearings may operate only if the misalignment
.of the inner ring in teference to the outer ring does not exceed 15'. If this type, of
bearing is installed in a' machine. assembly with less accurate alignment, the
24 ? STANKOIMPORT
AMI
expected life of the bearing will be sharply decreased and breakdowns due to the
overheating of the bearing or breakage of the retainer may -occur.
Alternative designs of the main type of single row ball bearings are:
a) Single row ball bearings with a filling slot or groove. Due to the increased
number of balls these bearings are capable of carrying larger radial loads but the
presence of the filling slot in the inner and outer rings does not allow the bearings
to carry increased thrust loads. Consequently, these bearings are more restricted
in their applications.
b) Bearings with a groove on the outside of the outer ring for a snap ring.
This design allows the bearing housing to be bored through without a
shoulder.
c) Single and double shielded bearings as well as bearings with built-in felt
or rubber seals. These bearings are to be used in bearing assemblies where a lack
of space provides difficulties in installing separate sealing devices in the bearing
housing or in cases where it is impossible to add lubricant to the bearings after
0*
installation. ?
Single row ball bearings find application in low power electric motors, gear
boxes of automobiles, tractors and machine tools, axle boxes of intra-works trans-
porting trucks, idle pulleys, conveyer rollers and other similar machine assemblies.

2. CYLINDRICAL ROLLER BEARINGS WITH
SHORT ROLLERS

the inner ring is disassembled.
Cylindrical roller bearings with short
rollers are available in a number of alternative i
designs:
1. Bearings, type 2000. Outer ring
straight, inner ring with two lips providing a
separable type of bearings in which the rollers i
and retainer remain on the inner ring. This
type of bearings is applicable in bearing
assemblies that require a floating support (the
outer ring may have axial movement along
the rollers). This type of bearing is only
capable of carrying a radial load; it cannot
carry a thrust load.
2. Bearings, type 32000. Inner ring -
straight, outer ring with two lips providing a
separable type. of bearings in which the rollers
and retainer remain in the outer ring when -ma
This type of bearings is applicable in bearing
assemblies that require a floating support (the inner ring may have axial movement
along the rollers). These bearings are also only capable of carrying a radial load,
they cannot carry thrust loads.
3. Bearings, type 42000. Inner ring with one lip, outer ring with two lips
providing a separable design in which the inner ring can be removed, and the
rollers and retainer remain in the outer ring. This type of bearings is applicable
in bearing assemblies requiring location of the shaft in one direction. These
bearings are capable of carrying radial loads.
4. Bearings, type 62000. Outer ring with two lips, inner ring with one lip and
with separate, loose lip of profiled cross section to provide separable type of
bearing in which loose lip is removed, inner ring is also removed and rollers and
retainer remain in the outer ring. This type of bearings is used when it is necessary
to locate the shaft in both directions. They can carry radial loads.
5. Bearings, type 92000. This type is similar to the preceeding type except
that the loos& lip has a rectangular cross-section. Bearings, type 92000, are also
capable of carrying radial loads and of locating the shaft in both directions.
6. Bearings, type 102 000. Inner ring with two lips, two retaining rings on
outer ring, full of rollers and without a retainer. This bearing is non-separable. It
carries only radial load; it does not carry thrust loads but outer ring is located
. axially in reference to the rollers by the retaining rings, For this reason, it is
unnecessary to secure the outer ring in the housing.
26 ? STANKOIMPORT
Cylindrical roller bearings with short rollers have larger radial load capacities
than ball bearings of the same size.
The selection of one or another of the alternative designs of roller bearings.
depends on the special' features of the given bearing assembly and demands
stipulated by mounting requirements.
Due to their separable design, cylindrical roller bearings with short rollers
are more convenient in mounting than ball bearings.
Cylindrical roller bearings with short rollers should be used in bearing
assemblies having short, rigid shafts which are not distorted by external stresses.
They should not be applied in assemblies in which misalignment of the inner and
outer rings are pcissible.
In cases, when a roller bearing having one ring without lips is used. for one
support of a shaft; a bearing locating the shaft in reference to the housings should
be used in the second support.
Cylindrical roller bearings with short rollers can be successfully applied in
the following machine assemblies: 'medium and high powered electric motors,
spindles of metalcutting machine tools, bearings of centrifugal pumps, axle boxes
of underground railway trains, tramways, railway rolling stock, etc.
Cylindrical roller bearings with short rollers having a bore diameter up to
100 mm are available with a retainer stamped of sheet steel. However, in accord-
ance with the size of the lot being produced, they are also available with a solid
retainer of non-ferrous metals. In operation both of these alternative designs are
equivalent in their capacities.

3. DOUBLE ROW SELF-ALIGNING BALL BEARINGS
Double row self-aligning ball bearings,',-:
type 1000, are designed in the main, for.-?;,:
carrying radial loads but, at the same time;
they can carry small thrust loads in botiC:i
directions.
It is not advisable to use these bearing'
for pure thrust loads, as in this case only ong
row of balls will be under load.
The thrust load, acting simultaneously:4
with the radial load should not exceed 20 per
cent of the non-utilized permissible radial,,
load at a given computed average life.
Type 1000 bearings, due to the features of.+
their design, can operate with considerable.'
misalignment (up to 30) of the inner ring in.:
Fig. 8
reference to the outer ring. This. misalignmen(
may be due to.the fact that the bearing seats:
are not in line or that the shaft is distorted by the action of the load.
As a consequence of their capacity, for sell-alignment, these bearings can be,
installed in machine assemblies with housings standing separately and with
misalignment of the axes of the bearing seats.
An alternative design of the type 1000 bearings is the 11000 type with a ?
tapered bore (taper 1 to 12) and installed on a clamping sleeve.
Bearings on clamping sleeves can be mounted on smooth shafts without;
shoulders and the shaft diameters for seating the bearings may be less accurately':
machined. The use of clamping sleeves considerably simplifies assembly and:
disassembly of the bearings. Besides this, the clamping sleeve allows some?
adjustment of the radial clearance in the bearing by expanding the inner ring;
slightly by means of the clamping sleeve.
Double row self-aligning ball bearings find wide application in agricultural'
machinery, fans, blowers, textile, knitting, paper-manufacturing and otheri
machinery.
4. DOUBLE ROW SELF-ALIGNING ROLLER BEARINGS
Double row self-aligning roller bearings
have a type designation of 3000. These bearings
have the largest load capacities of any bearings
of the same dimensions.
Self-aligning roller bearings can simul-
taneously carry a? thrust load in either
direction besides the radial load.
The thrust load, acting together with the
radial load should not exceed 20 per cent of
the non-utilized permissible radial load.
The self-alignment capacity of this
bearing is the same as for double row self-
aligning ball bearings.
An alternative design of this type of
bearing is bearing type 13000 with a tapered
bore (taper 1 to 12) which can be mounted
either directly on a tapered seat of the shaft
or on a smooth cylindrical shaft by means of an intermediate clamping sleeve
clamping-stripping sleeve or adapter.
Double row self-aligning roller bearings are used as supports for long multi-
support shafts subject to considerable* deflection under the action of external
loads, as well as in machine assemblies where the bearing housings stand separately
and it is not expedient to arrange the housings on a common baseplate.
This type of bearing can be successfully applied in assemblies of the following
machines: coal-cutting combines and coal-cutters; centrifugal blowers, pumps and
draught fans; rolling mills and medium and high power reducing gear units, log
frames; travelling truck wheels and wire rope pulleys of port cranes; screens and
rock crushers and many other types of machines in which the bearings are subject
to heavy loads.

5. ANGULAR-CONTACT BALL BEARINGS
(Types 6000, 36000, 46000 and 66000)
6. NEEDLE ROLLER BEARINGS
These bearings are designed to withstand
combination loads acting in both the radial
and axial directions.
A single row bearing of this type may
resist pure thrust loads acting in one direction.
To locate the shaft in both directions this type
of bearing must be applied in pairs (duplex
installation).
Installation of these bearings in pairs
allows the unit to be preloaded.
For withstanding large thrust loads, a
number of these bearings .may be installed
one after another (narrow face of the outer
ring of one bearing against the wide face of the
outer ring of the other bearing) in the so-
called "tandem" arrangement.
When properly selected so as to ensure a
uniform distribution of the load between the separate bearings, such a set of
bearings may withstand a very considerable load and each bearing carries that
part of the load obtained by dividing the total load by the number of bearings in
the set. The limiting speed of a group of bearings equals the maximum allowable
speed of the component bearings.
This type of bearing can be applied in assemblies having rigid two-support
shaft with a comparatively small distance between the supports. They can also be
used in assemblies that require adjustment of the internal clearance in the
bearings during mounting and in operation.
The applications of angular-contact ball bearings include: spindles of
machine tools and woodworking machinery, electric motors, centrifuges, worm
gear reducing units, front wheels of automobiles, magnetos, etc.
(Type 74000)
Needle roller bearings are designed for
resisting only radial loads. Due to the small
diameter of the rollers (needles), these
bearings have smaller outside diameters when
compared with other bearings having the
same bore diameters.
This type of bearing, in accordance with
the features of design of the bearing assem-
bly, may be used without either an inner or
outer ring or even without any rings, merely
using a set of needle rollers. In these cases the
roller races in the housing or on the shaft
should possess the same qualities as the
bearing ring (as to hardness, accuracy and
finish). This bearing does not locate the shaft
or housing axially and is very sensitive to
misalignment of the seating surfaces. The
bearing seats for two support needle roller bearing assemblies must be bored in
a single set-up.
Needle roller bearings find application in machine assemblies, where space is
limited, and are often used in oscillating machine members.
To provide reliable working capacity, bearings in oscillating assemblies should
be lubricated with fluid mineral oil.
Machine assemblies in which needle roller bearings are widely used include:
universal joints of. automobiles, piston pins, connecting rod pins, engine camshafts,
rocker arms of distributor mechanisms, supports of crank-arm mechanisms, etc.

7. FLEXIBLE ROLLER BEARINGS
8. TAPER ROLLER BEARINGS
These bearings are designed for withi,
standing only radial loads. They do not locate
the shaft or housing axially. These bearings;
however, are capable of resisting impact loads.:,
Flexible .roller bearings are' available ir
two types: Type 5000 having two solid rings!
and a set of rollers held in a retainer and,
type 45000 with a stamped split outer ring
and a set of rollers held in a retainer.
Other modifications of the main type 5000:
are available as a bearing with one solid outer,
ring and a set of rollers in a retainer and
known as type 35000 as well as a roller
assembly in a retainer and without rings,
type 65000.
Fig. 12 Flexible roller bearings are used in
machine assemblies where accurate rotation
is not essential, as for instance: intra-works transportation facilities, various
assemblies of agricultural machinery, combines, ploughs, working and transporting
rolls of roller tables for rolling mills, etc.
Taper roller bearings are, in fact, radial..
thrustbearings designed for withstanding
combination loads (radial and thrust).
If two bearings are mounted adjacent to
each other or at the opposite ends of a two-
support shaft, they can carry pure radial loads.
Taper roller bearings are manufactured
with interchangeable outer rings or cups. As
the outer ring (cup) is separable, these bearings
are convenient for separate mounting the
outer ring in the housing and the inner ring
(cone) and rollers on the shaft.
Alternative designs of the single row
taper roller bearing, type 7000, are: -
Type 67000 with flange on outer ring
(flanged-cup);
Type 27000 with large taper angle of
outer ring (cup) in a range from 25? to 29';
Types 37000, 97000 and 47000 are double row roller ? bearings, without and
with axial clearance adjustment, respectively;
Type 77000 is a fourrow roller bearing.
Single row taper roller bearings are to be used in machine assemblies having
rigid two-support shafts with a comparably short distance between the supports.
The bearing allows for the adjustment of axial clearance during mounting, as well
as in operation.
It must be stressed that these bearings react very sensitively to the working
axial clearance. Excessive tightening will result in a sharp raise in temperature
while on the other hand excessive axial clearance may bring about bearing failure.
Consequently, during both initial mounting and subsequent operations, it is
necessary to adjust the axial clearance with special care.
Double and fourrow taper roller bearing S are manufactured with a certain
amount of axial clearance incorporated in the bearing and are not to be adjusted
during mounting operations.
The increase in axial clearance in these bearings due to wear in operation is
compensated for by grinding down the spacer rings.
Taper roller bearings find application in the following assemblies of various-
machinery :

9. BALL THRUST BEARINGS
Both single and double ball thrust:
bearings are available.
Single thrust bearings, type 8000, are:.
designed for carrying a thrust load in one:
direction.
Double thrust bearings, type 38000, are
designed for carrying thrust loads in both
directions.
The single thrust bearing consists of two
rings and a set of balls in a retainer. The
revolving or "tight" ring of the bearing is,
mounted directly on the shaft with a suitable
fit while the second, stationary or "loose" ring,,
is mounted in the housing. The bore of the?
"loose" ring, as a rule, is larger than the bore of
Fig. 14 the "tight" ring by an amount approximately
up to 1 mm.
As a lack of coincidence of the axes of the housing and shaft may result
in premature bearing failure, it is advisable to provide self-alignment of the
rings by mounting the "loose" ring in the housing with a clearance in the order
of 0.4 to 0.6 mm on the diameter. This clearance will compensate for any -
misalignment between the axes of the housing and shaft.
To eliminate the effects of mounting misalignment of the bearing rings due ,
to a lack of squareness of the housing shoulder to the shaft axis, it is advisable to,
arrange spacers of some plastic material under the "loose" ring. Such spacers may
be made of linoleum, leather, oil-resistant rubber (sevanite), etc.
SSW
34 ? STAN KOIM PORT
Double ball thrust bearings consist of one "tight" or rotating ring with two
ball races, two "loose" or stationary rings and two sets of balls in retainers.
Ball thrust bearings with spherical seating rings, single, type 18000 and
double, type 848000, are non-standard types and not advisable for application in
newly designed assemblies. This is due to the excessive sliding friction between
the spherical surfaces of the bearing and seating rings which sharply limit their
self-aligning properties.
During operation, under, the action of c.entrifugal forces, the unloaded row of
balls, especially in double row bearings, has a tendency to run out of the races.
This shifts the axes of rotation of the balls and causes sliding friction between the
balls and races. This latter results in overheating and failure of the surfaces of
the balls and races. To avoid this, it is advisable to provide a constant. load on the
unloaded balls and "loose" ring by means of continuously acting springs.
In many machine assemblies, to withstand thrust loads, it is possible to use
single row ball bearings by selecting the bearing to suit the thrust load.
Ball thrust bearings are used in the assemblies of the following machines:
vertical centrifuges, low-speed reducing gear units transmitting large torques,
crane hooks, machine tool spindles, pivots of rotary cranes, live centers of machine
tools, jacks and other machinery.

SPECIFICATIONS
3. The accuracy of the dimensions of bearings are determined by the tole-;
rances of their chief dimensions such as the bore, outside diameter and widti-i,c
of rings.
A.? J
The accuracy of running of bearings is determined by the following runout",
components:
a) radial runout of outer, inner and tight rings;
b) axial runout of faces of inner ring;
c) axial runout of raceways of inner and outer rings.
IS
4. Tolerances for the bores and outside diameters, widths, parallelism of faces
as well as for radial and axial runout of rings, for each class of accuracy, are given
in Tables 12, 13, 14, 15 and 16.
5. As a result of out-of-roundness, taper and other deviations from an exact:
cylindrical surface, during measurement different values are obtained for the'
diameter in one or several sections.
'
The effective deviations of maximum (d. and Dmax), minimum (drain and:
Dmin) and mean (dm and Dm) diameters in accordance with the accuracy classd-
must be within the limits indicated in Tables 12, 13, 14 and 15.
The mean diameter is defined as the arithmetical mean of the maximum and
minimum diameter measurements:
dmax drain
dm ?
2
? Dmax Drain
Dm ?
2
or
Example : For a nominal bore diameter
accordance with Table 12 are:
d = 100 mm, the limits
high limit for mean diameter dm ? zero;
low limit for mean diameter dm ? minus 0.02 mm;
high limit for maximum diameter dmax ? plus 0.005 mm;
low limit for minimum diameter dull,' ? minus 0.025 mm.
consequently:.

38 ? STANKOIMPORT
11119112
If during measurement, dmax' turns out to be equal to 99.998 mm and driii? =
99.976 mm, the bearing is considered as within the limits in reference to the
bore, as:
99.998 + 99.976
dm ? = 99.987 mm is within the indicated limits (100.000 and
2
99.980 mm); dm, does not. exceed 100.005 and drift is over 99.975 mm.
If, however, during inspection d. = 100.004 mm and drain 99.998 mm the
bearing is not within the bore limits, as:
100.004 + 99.998
dm ? = 100.001 mm. This exceeds the indicated limits (100.000
2
99.980 mm) even though dmax is less than 100.005 nim and dmin exceds 99.975 mm.
6. The mounting height dimensions of angular-contact ball bearings should
not be beyond the limits stipulated in the standards.
MARKING AND LUBRICATING OF BEARINGS
7. Each manufactured bearing should have the trade mark of the manufactur-
ing works as well as the bearing symbol (according to GOST 3189-46) indicating
the type, size and class of accuracy of the bearing.
8. Separable ball and roller bearings are marked on both rings.
9. All supplied bearings are to be lubricated with a protective lubricant and
should be carefully wrapped separately in moisture-proof paper.
The initial lubrication and packing of bearings, if they are subsequently
properly storaged, will ensure protection from corrosion for a period of 12 months.

Notes: 1. For replacing ball and roller bearings during repairs of automobiles, tractors, agricultural and other machinery,
if the bearing seats on the shafts show mounting wear, bearings may be manufactured in the standard class of accuracy but with the
tolerance zone of the bore shifted toward the minus direction by a value equal to the tolerance on the mean diameter. Such bearings
are marked with the letter "M" placed before the bearing number.
2. For ball and roller bearings with tapered bores, the nominal bore diameter is defined as the minimum diameter of the taper.
3. The permissible taper of the bores of ball and roller bearings, classes B and B11, should not exceed 500/0 of the tolerance on
dm (mean diameter).
4. Tolerances on the width a inner rings of ball and roller bearings with tapered bores, as well as on the width of outer rings
of taper roller bearings are not standardized but the upper limit of the ring width is the nominal value.
5. The tolerances for axial runout of faces and raceways are given for inspection with the bearing mounted on a mandrel.
6. Axial runout, a rings of self-aligning bearings and radial roller bearings is not checked.
7. Permissible axial runout of faces and out-of-parallelism of inner rings with tapered bores is not checked.
8. The radial runout of inner rings of ball and roller bearings designed to be mounted on clamping or stripping sleeves
should not exceed 150% of the values given in Table 12 and the deviation of the diameter "d" - 300 oh a the values given in this
table for the mean diameter "dm" with a sign ; the out-of-roundness of the bore should not exceed the tolerance zone of
",1,c1max" and "drain" of the table.

INSTRUCTIONS FOR SELECTING
ANTIFRICTION BEARINGS
GENERAL INSTRUCTIONS
In the selection of the type and size of ball and roller bearings the following
factors are to be considered:
a) The magnitude and the direction of the load (radial, thrust or combined
see Fig. 18 a, b and c);
Radial
Thrust Comoined
Fig. 18
b) The nature of the load (constant, variable, or impact);
c) Speed of rotating ring of bearing (r. p. m.);
d) Desired life (expected term of service expressed in hours);
e) Surrounding atmosphere (temperature, humidity, acidity, etc.);
f) Requirements arising from the design of the machine assembly (necessity
for self-alignment to compensate for shaft or housing misalignments, provision
for axial movement of shaft, the desirability of mounting the bearing directly on
the shaft or on either a clamping or a clamping-stripping sleeve; necessity for
adjusting radial and axial clearance of bearing, available space for the assembly,
rigidity, accuracy of running, etc.);
g) Cost of the bearing.
48 ? STANKOIMPORT ?
This last factor is very important in decreasing the cost of the machine as a
whole. For this reason, it is inexpedient to use more expensive double row self-
aligning roller bearings if it is possible to ensure normal operation with other
types of bearings as for instance, self-aligning radial ball bearings or bearings
with cylindrical rollers. With the same aim in view bearings of standard accuracy
should be used when possible and for assemblies which do not require accurate
running, bearings class "0" or "HO" should be used (see GOST 4793-49).
When selecting bearings, it is not advisable to fix an excessively large term of
service (expected life) as this surplus capacity increases the size of the selected
bearing and consequently will result in the development of a heavy and expensive
machine.
T following sequence. should be observed in selecting bearings:
a) The type of bearing is selected proceeding from the operating conditions
and design of the given bearings assembly in accordance with the directions given
in the section "Characteristics of the Main Types of Antifriction Bearings" of this
catalogue;
b) The size of the bearing is determined in accordance with the acting loads,
speed and required term of service;
c) The class of accuracy of the bearing is established taking into consideration
the requirements for the accuracy of running of the assembly.
The required size of bearing is chosen by means of its capacity coefficient "C".
This coefficient is the most essential rating basis of the bearing and depends upon
the internal construction of the bearing, the material used in its manufacture and
a number of other factors.
In order to insure uninterrupted function of the bearing unit at high speeds
(in this case the acting loads should be of moderate rate) not only the correct
design and type of bearing is to be considered but special attention must be paid
to the bearing unit design, to the seating surfaces of the bearing and to the bearing
lubrication which should correspond to the adequate operating conditions.
Mounting conditions for high speed units are of decided importance and in
particular clearance adjustment of angular-contact bearings.
Therefore, if the machine designer has no sufficient experience in solving all
these problems it is suggested that tlie Supplier be consulted.
COMPUTATION OF THE EXPECTED LIFE OF BEARINGS
The expected life of a bearing is understood to be that period of time,
expressed in hours of operation, for which not less than 90 per cent of a lot of
bearings should operate, at identical conditions, without showing any traces of
fatigue of the metal. Typical signs of fatigue are traces of crumbling of metal on
the working surfaces and apparent as pitting or scaling (flaking)*.
* See GOST 520-55, paragraph 19.

Declassified in Part - Sanitized Copy Approved for Release 2013/08/13: CIA-RDP81-01043R002200240001-6
The expected life of any given bearing depends on the magnitude and direction
of the loads, speed, capacity coefficient and a number of other factors, effect of
which on the expected life will be taken up lower.
The relation between the computed life expectancy "h", equivalent load "Q",
speed "n" and capacity coefficient "C" is expressed by the following empirical
equation:
Q (n ? h) " C (1)
This formula is valid for speeds of n> 10 r. p. m. but not exceeding the
limiting speed permissible for any given bearing. For speeds "n", from 1 to
10 r.p.m. "C" is Calculated as for 10 r.p.m. For n< 1 r. p.m., the load is considered
to be static and, in the selection of a bearing, is compared with the permissible
static load of a given bearing.
The capacity .coeffipient, limiting speed and permissible static loading for
standard bearings, excepting flexible roller bearings, are indicated in the bearing
dimension tables of this catalogue.
Due to the special conditions met with the computations for flexible roller
bearings, this catalogue indicates the permissible loads for such bearings.
The capacity coefficient for bearings without rings is indicated in the catalogue
for conditions in which the surface hardness of the bearing race in the housing or
on the shaft is not less than R, ? 60.
EQUIVALENT LOAD
The equivalent load Q takes into consideration the nature and direction of
the load, as well as special features of the kinematic arrangement and temperature
conditions of the assembly.
For radial bearings the equivalent load is defined as:
Q = (R ? Kk rla ? A) Kb ? Kt (2)
for radial-thrust bearings as:
Q [R ? Kk m (A?S)] Kb ? Kt
and for, thrust bearings as:
(3)
Q A ? Kb ? Kt (4)
The values included in the for^ mulae (2, 3 and 4) are defined as follows:.
R ? radial load in kg;
A ? thrust load in kg;
S ? axial force (reaction) appearing in the bearing as a result of the radial'
load (existing only in the installation of radial-thrust bearings);
50 ? S TAN KO I M POR T
m ? coefficient which takes into account the different effect of the radial
and thrust load on the bearing term of service;
Kb ?? coefficient which accounts for the effect of the nature of the load on
the bearing term of service;
Kt ? coefficient which takes into consideration the temperature condi-
tions ar.:1 its effect on the term of service;
? coefficient which accounts for the effect of which of the bearing rings
rotates in reference to the load vector upon the term of service.
The values of the coefficients 1(1,, Kt, Kk and m are indicated in Tables 22, 23,
24 and 25.

SELECTION OF RADIAL BALL AND ROLLER BEARINGS
These bearings are selected with the aid of the formula:
C = (R ? Kk M ? A) Kb ? Kt (n ? h) ??3.
(5)
This formula is obtained by combining equation 1 and formula 2. To facilitate
computations, the value (n ? h)0.3 may be taken from Table 28.
An example of the selection of a radial ball bearing as follows:
Considering the operating conditions of the assembly, a single row ball bearing
has been chosen. It is subject to the following loads: radial R -=-? 550 kg and
thrust A = 270 kg at a speed of the outer ring of n ??= 1250 r. p. m. The load vector
is stationary in reference to the inner ring. During operation the bearing is subject
to light shocks and small short-time overloads. The working temperature of the
bearing does not exceed 100? C. The desirable expected life is 5000 hours.
It is necessary to determine the size of the bearing, suitable for the above
conditions, if the shaft has a diameter of 95 mm.
The capacity coefficient is determined from formula:
C = (R ? Kk + m ? A) Kb ? Kt (n? h)
where: Kb = 1.2 (see Table 22),
Kt = 1.0 (see Table 23);
Kk = 1.4 (see Table 24).
Coefficient "m" is determined from Table 25 which indicates m = 1.5;
R 550
however, since ?A ?270 2, "m" is to be inpreased by 150/0. The final value
is m = 1.5 ? 1.15=1.725.
Substituting these values of the coefficients in formula (5), the value of Coef-
ficient "C" is determined:
C := (550 ? 1.4 + 1.725 270) 1.2 ? 1.0 (1250 ? 5000) 03
according to Table 28, (1250 ? 5-000) 0.3 = 110 and consequently C 180000,

Declassified in Part - Sanitized Copy Approved for Release 2013/08/13: CIA-RDP81-01043R002200240001-6
Therefore, the given working conditions require a bearing capacity of which
coefficient "C" is not less in value than 180000. The single row ball bearing,
number 319, fully satisfies this requirement.
On the selection of cylindrical roller bearings only the radial load is taken -2
into consideration in accordance with the formula:
C = R ? Kk ? Kb ? Kt (n ? II) 03. (6)
?
As a rule, these bearings are to be used in machine assemblies where they are
subject only to a radial load. Certain designs of cylindrical roller bearings can,
if necessary, withstand small accidental thrust loads which can be neglected in
expectant life computations.
SELECTION OF RADIAL-THRUST BEARINGS
The formula for the selection of radial-thrust bearings is:
C [R ? Kk (A-S)1 Kb ? Kt (n ? h) 0.3. (7)
Due to the angular-contact between the balls or rollers and the rings, the
action of the radial load in radial-thrust ball or roller bearings creates a force S
directed along the shaft axis (Fig. 19). This force, to some extent, relieves the
bearing of the acting thrust load.
TR
Fig. 19
alt?;
In some cases, with a definite ratio of radial loads on two bearings installed
with unlike faces (tandem arrangement) toward each other, these axial forces
compensate each other and consequently need not be taken into consideration in
the computations. The equivalent load Q is then determined from formula (2).
52S
STAN KOIM PORT ?
If the axial components do not compensate each other, the equivalent radial load
is computed by one of the formulae of Table 26. These formulae have been
compiled for various arrangements of. radial-thrust bearings and various ratios of
radial load R, thrust load A and axial component S. The value of the axial
component S of the radial load R is computed from the formula:
S 1.3 R tg
where 13 is the angle of contact _between the balls or rollers and the race of the
outer bearing ring.
Approximate values of the angle 13 are:
Angular-contact ball bearings, type 36000 ? 12?, type 46000 ? 26?, type
66000? 36?.
Taper roller 'bearings, type 7000? 110 to 15?, type 27000 ? 25? to 29?.
The value of coefficient "m" for tentative computations can be taken from
? e
Table 25. For more exact computations, it can be determined from the formula:
1
6
m?
2.6 tg (3 ?
In selecting double row or fourrow taper roller bearings, in case of thrust
loads the latter are considered to be carried by only one row of rollers.
The capacity coefficient of one row of rollers is determined by dividing the
tabulated coefficient "C" by 1.70 for double row and by 3.0 for fourrow bearings.
The equivalent load for double row taper roller bearings is computed from
the formula:
= 0.5 R + 0.4 A cOtg 13.
The following is an example of the selection of radial-thrust ball bearings: two
angular-contact ball bearings are to be installed in the assembly in an arrange-
ment illustrated by Fig. 20. The following loads act on the bearings: R1 --= 108 kg,

112= 210 kg and A = 90 kg at a shaft speed of n = 5000 r. p. m. The load vector;
moves in relation to the inner ring. During operation, the bearing is subject to ?;
moderate shocks of a vibrating load. The working temperature does not exceecO,
60? C. The desirable expected life is 2000 hours. The shaft is 40 mm in diameter. z
It is necessary to determine the sizes of the bearings suitable for the given ?
conditions.
In this case R1 0 and consequently the equivalent loads should be
determined in accordance with arrangement 15 of Table 26, which indicates:
a) for bearing 1:
Q1 = R1 ? Kk Ill [A + (S2 ? S1) ] Kb ? K.
For angular-contact ball bearings with a contact angle of 26?, m = 0.7 '
(Table 25). The axial components S of the radial loads are determined from the
formulae: S1 = 1.3 R1 tg 131 and S2 = 1.3 R2 tg (32. For a contact angle of 26?,
tg 13= 0.487, then:
= 1.3 ? 100 ? 0.487 = 63 kg
S2 = 1.3 ? 210 ? 0.487 = 133 kg.
Under the given conditions the following coefficients are valid for both
bearings:
Kb = 1.5 (Table 22);
Kt = 1 (Table 23),;
Kk = 1 (Table 24).
Therefore: C11 = {100 ? 1 + 0.7 [90 + (133 ? 63)11 ? 1.5 ? 1.0
Qi = 318 kg
The capacity coefficient of bearing 1 should equal:
C = Q (n ? h)??3; C --=-? 318 (5000 ? 2000)0-3P-- 40000.
This capacity coefficient, for an angular-contact ball bearing with a bore of
40 mm, corresponds to bearing number 46208 with dimensions 40X80X 18 mm.
b) for bearing 2:
Q2, = 112 ? Kk ? Kb ? Kt
and after substituting the numerical values:
Q2 = 210 ? 1.0 ? 1.5 ? 1.0
Q2 = 315 kg. ,
54e STANKOIMPORT
The required capacity coefficient is determined from the equation:
C = Q2 (n..h) "
C = 315 (5000 ? 2000)??3 =-- 40000. -
This corresponds to the same bearing, number 46208, as for the first support.
An example of the selectiqn of a double row taper roller bearing as follows:
a double row taper roller bearing with a bore not less than 120 Mrn is to be
selected to suit the following operating conditions: R= 2400 kg, A= 350 kg,
n =-- 250 r. p. m.; the shaft rotates (the inner ring moves in relation to the load
vector). The load includes heavy shocks and short-time overloads up to 3000/0, the
expected bearing temperature is 150? C and the desirable expected life is
5000 hours.
The capacity coefficient is determined by the formula:
1.7
? (0.5 R ? Kk + 0.4 A cotg (3) Kb ? Kt (n? h)"
where Kb = 3 (Table 22);
Kt = 1.1 (Table 23);
Kk =-* 1 (Table 24);
then: C = 1.70 (1200 -I- 0.4 ? 350 ? 5.67) ? 3 ? 1.1 (250 ? 5000)??3
and C = 756,000.
This capacity coefficient corresponds to bearing, number 2097726, having a
bored= 130 mm.
SELECTION OF THRUST BEARINGS
The formula for the selection of thurst bearings is obtained by transforming
the formula (5) in which R = 0 and m = 1 for thrust bearings.
Then: C =-- A ? Kb ? Kt (n ? h)??3. (S)
The procedure' for selecting the bearings does not differ from that for radial
and angular-contact bearings.
SELECTION OF BEARINGS OPERATING UNDER VARIABLE LOADS
AND AT VARIABLE SPEEDS
Bearings for assemblies where the load and speed are variable (speed gear
box shaft bearings, rope drums, etc.) are selected by means of the equivalent
variable cycle load QE.V. c, and the equivalent speed neq?

accuracy from the formula:

The equivalent load, used when selecting the bearing, is defined as:
Q =-? QE.V.C. ? Kb ? Kt ? Kk?
If a combined load is acting on the bearing, the equivalent load is first
computed from formula 2 or the formulae given in Table 26.
An example of the computation of the equivalent variable cycle load as
follows:
The bearing operates under the following variable conditions:

Q2= 270 kg;
Q3= 70kg;

n2 --= 1075 r. p. m.

BEARING SELECTION FOR STATIC LOADS
If a bearing under load is stationary or rotates at a speed less than 1 r. p. m.,
it should be selected in accordance with its static load capacity.
The bearing data tables in this catalogue include values of the static load
capacity of bearings or, as it may be called, the permissible static load QST. Loads
acting on the bearing should not exceed its static load capacity.
If a bearing operates under impact load or special accuracy of running is
required, the permissible static load QST of the selected bearing should be twice
the acting load.
BEARING SELECTION BY MEANS OF THE EQUIVALENT LOAD TABLE
Besides the bearing data tables, which include the capacity coefficient "C",
Table 29 indicates the permissible loads Q in accordance with the speed 7 "xi"
and the value "C" for a computed expected life of h = 5000 hours.
If it is necessary . to select a bearing for some- other expected life, the
correction factor Kg is added to the formula for computing the equivalent load Q.
This factor depends on the value of the desirable expected life. Values of the
. correction factor Kg are given in Table 27-.
The corresponding capacity coefficient is determined from Table 29 in
accordance with the 'computed equivalent load Q and the given speed "n". Using
this capacity coefficient and the tables of bearing data, the required size of bearing
is selected.
?
.58? STANKOIMPORT ?
An example of the selection of a bearing using the equivalent load table as
follows: .
-The operating conditions require a single ball thrust bearing, on a shaft
120 mm, subject to a thrust load of 1700 kg at a shaft Speed of 500 r. p. m. The
load acts with considerable shocks and vibration. The temperature is not over
50? C and the desirable expected life is 2000 hours.
It is necessary to determine the size of the bearing.
The equivalent load is determined from the formula:
Q = A ? Kb ? Kt ? Kg
where: Kb 7=-- 2.0 (Table 22);
Kt =-?-? 1 (Table 23);
Kg = 0.78 (Table 27);
then Q = 1700 ? 2 ? 1 ? 0.78 = 2652 kg
This load at a speed of 500 r. p. m. in Table 29 corresponds to a capacity
coefficient of 220000.
Using this value, the bearing, number 8224, having dimensions of
120X170X39 mm, is selected from the ball thrust bearing data table.

MAIN INSTRUCTIONS FOR SELECTING FITS
FOR ANTIFRICTION BEARINGS* -
GENERAL PRINCIPLES
The selection of the nattire of the fits between the bearing rings and the shaft-,
or housing, that is, the selection of the shaft and housing fits, for the most part
.
depends on the magnitude, direction and nature of the bearing loads; the type and
size of the bearing and its mounting arrangement in the assembly, as well as the
class of. accuracy of the bearing.
The nature of the stress distribution inside the bearing differs for the inner
and outer ring and consequently different fits are required, as a rule, in the housing
and on the shaft.
The working conditions of the inner and outer rings depend mainly on
whether the given ring is stationary or rotates in relation to the radial load on the
bearing. In this connection, the following types of ring loading are distinguished:
local, circulatory and oscillatory.
Local loading is defined as an arrangement in which the load on the bearing.
is being constantly carried by a limited portion of the race and is transmitted to a
limited section of the bearing seat on the shaft or in the housing. This type of
loading occurs when the given ring does not rotate in reference to the load.
An example of local loading is the loading of the stationary outer ring at a
load, constant in direction, and a rotating inner ring.
Circulatory loading is one in which the load on the bearing is consecutively
carried by the whole circumference of the race and is transmitted consecutively
to the whole circumference of the bearing seat on the shaft or in the housing.
This type of loading can be observed when a given ring rotates in reference
to the constant direction of the load or when the direction of the load varies
(rotating load) in reference to the stationary ring. An example of circulatory
loading is the load on the rotating inner ring at a constant direction of the
bearing load.
Oscillatory loading is one in which a load of constant direction acts together
with a rotating load on the bearing and the resultant load does not make a full
revolution but oscillates in a definite portion of the statiOnary ring. The bearing
seat on the shaft or in the housing has the same type of loading.
The types of loading of rings in accordance with the operating conditions are.
indicated in Table 30.
* For more detailed information see GOST 3325-55.

BEARING FITS
The bearing fits on shafts are in the basic hole system of fits while. in housings
they are in the basic shaft system. It is necessary to point out that the bearing
bore limits, as stipulated by GOST 520-55, are to the minus side of the nominal
bore while the hole limits for the basic hole OST system are arranged to the plus
side. Consequently, the class of fits obtained for the inner rings of bearings on
shafts, machined to standard transition fit gauges (in accordance with OST NKM
1011 and OST 1012), differs from the standard fits of shafts in the basic hole system
in that the former are more tight.
- In accordance with the required class of fit of the bearing bore on the shaft,
the shaft tolerances are selected from the following series of basic hole r1, T1, HI,
III and C1 (extra fine force, drive, wringing and slide fits, respectively) in accor-
dance with OST NKM. 1011 (Table 36); r, T, H, U, C, A and X (fine heavy force,
force, drive, wringing, push, slide, easy slide and normal running fits, respectively)
in accordance with OST 1012 (Table 38).

If bearings are to be mounted on taper clamping or clamping-stripping sleeves,
the shaft should be machined to the tolerances for the fit B3 (plain basic shaft fit)
in accordance with OST 1023. In assemblies, which do not require accurate running'',
the shaft may be machined to the tolerances for fit B3a (extra-plain basic shaft k'
in accordance with OST NKM 1027 or B4 (rough basic shaft fit) in accordance wiA'
OST 1021.
In accordance with the required class of fit of the bearing outside diameter
the housing, the housing bore tolerances are selected from the following series of'
basic shaft fits: ri, Ti, Hi, Hi and C1 (extra .fine force, drive, wringing, push arid
slide fits, respectively) in accordance with OST NKM 1021 (Table 37); r, T, H, II;
C and (fine heavy force, force, drive, wringing, push, slide and easy slide fits)
according to OST 1022, C; (plain slide fit) according to OST 1023 and P7 according
to ISA-3 (Table 39).

When mounting radial bearings having a class of accuracy A or C only'extra -
fine tight or slide fits should be used.
At, high speeds and local loading, the shaft or housing should be machined to
the gauge for fits for H.
FITS FOR NEEDLE ROLLER BEARINGS
Needle roller bearings with solid rings are to be mounted on shafts and in.
housings with the sanie fits as radial bearings.
76 ? S TAN KOIM POR T ?
For needle roller bearings with thin, stamped (split) outer rings, it is advisable
to machine the housing seats to the fine fit gauges II for housings of steel or cast-
iron or H for housings of aluminium or light alloys. . .
In some cases, when mounting needle roller bearings with thin, stamped
outer rings, a selective assembly system is recommended according to which the,
bearings and housings are segregated into groups within the limits of the total
tolerance on the diameters. The bearings are then assembled into the housings of
the corresponding groups. This avoids excessive interferences or clearances.
The following tolerances are recommended for machining shafts (race surface
for the needles):
For rotation of the bearing ? fine basic shaft fit B; for small-amplitude
oscillations and static loads ? fine fit to gauge H (fits according to OST 1022).
Note; Heavily loaded needle roller bearings, as well as other types of?bearings, should
not be mounted directly in housings of light alloys. In such cases, the use of an intermediate
steel sleeve is recommended.
Fits for Radial-Thrust Bearings
The following fits are recommended for radial-thrust bearings in accordance
with the load and type of loading:
Ring and type of loading
Fits
Non-adjustable circulatory loaded rings of all
r?, T?, H?, 'T,, for shaft and
classes of accuracy
housing and P7 for housing
Adjustable circulatory loaded rings (bearing
assembly design not recommended)*
H?
Adjustable or non-adjustable locally loaded rings
which do not move directly on the seating surface
IL, C? for shaft and T?, Hn,
C? for housing
Adjustable locally loaded rings
C?, -,gn, Xn for shaft and Cn
for housing . .
N o t e: The fits for the rings of paired (duplex) bearings, which have been preloaded
during manufacture, should be specially stipulated.
* The material of the bearing seats shouldbe of increased hardness; the bearing seats
on the shaft should be hardened and special hardened sleeves should be inserted into the
housing.

AXIAL CLAMPING AND RETAINING METHODS FOR ANTI.
FRICTION BEARINGS MOUNTED ON SHAFTS OR IN HOUSINGS
Endwise movement of bearing rings along the bearing seats, under the action
of a thrust load, can be prevented by employing shaft end or intermediate
damping members to retain the inner ring on the shaft.
The larger the magnitude of the thrust load and the higher the speed of one
of the bearing rings, the more reliably should the bearing ring be clamped.
The most widely used methods for axially clamping the inner and outer
rings of bearings in their assemblies are illustrated lower and accompanied by
brief descriptions.
1. CLAMPING INNER RINGS
Clamping by means of a tongued lock washer and a locking nut in which the
inner tongue of the washer enters a slot in the shaft and one of the external wings
is bent into a slot of the nut (Dimensions of nuts and lock washers are in accord-
ance with OST 26002) (Fig. 21).
Clamping by means of two nuts, one of which acts as a lock nut. A lock washer
is installed between the nuts to avoid rotation of the main nut when the lock nut
is being tightened (Fig. 22).
Retaining by means of a split ring (of 2 halves). After installation in a groove
of the chft, the halves are fastened together with wire (Fig. 23).

SEALS AND CLOSURES
Seals and closures of bearing assemblies are designed to prevent the loss of
lubricant from the bearing and to protect it from dust, dirt, moisture, acid fumes
and other injurious matter which may enter the bearing.
Insufficient protection of the bearing from the surrounding atmosphere or
adjacent machine parts may considerably shorten its term of service. Besides this,
the leakage of lubricant is not only detrimental to normal operating conditions'
for bearings but soil the mechanism and often result in spoilage of the product
manufactured on this machine.
?
The construction of a sealing device or closure should be as simple as possible
but at the same time it should be sufficiently reliable for the given operating
conditions.
The more complex and expensive designs of seals and closures can be suitably
applied only for heavy bearing duty when the use of the simpler types of closures
will not ensure normal operation of the bearing.
The more widely used types of sealing devices and closures for bearings are:
1. Felt seals;
2. Annular clearances and grooves (grease grooves);
3. Protective washers or flanges;
4. Oil slinger rings and grooves;
5. Cup seals;
6. Labyrinths closures.
The selection of a proper type of bearing seal depends on:
1. The nature of the surrounding atmosphere;
2. Design features of the bearing assembly;
3. Speed of the bearing (peripheral speed on shaft);
4. Type of lubricant: fluid (mineral oil) or grease;
5. Operating temperature of bearing.
Fig. 41 a illustrates the most common designs of single and double ring felt
seals for split housings while Fig. 41 b shows a felt seal arranged in the
removable cover of the housing.
A seal design providing for periodical or constant compression of the felt
ring to compensate for wear is shown in Fig. 42.
Felt seals are, for the most part, designed to protect bearings operating in not
very dusty conditions and with grease for lubricant. They can, however, be used
90 ? STANKOIMPORT ?
in a combination with other types of seals for fluid lubricant. Fig. 43 illustrates
a combination system of sealing; an oil slinger flange has been added to the felt
seal. This flange, during rotation, throws the oil into a recess in the housing cover
a
Fig. 41
Fig. 42
and so prevents leakage. The narrow annular clearance between the shaft and the
housing cover is filled with grease. This increases the reliability of the seal in
protecting the bearing from dirt from the outside. ?
The devices illustrated in Figs. 41 to 43 may be employed for mechanisms
operating in a comparatively clean and dry'surrounding atmosphere.
The closure illustrated in Fig. 44 is a combination of a felt seal and a laby-
rinth. The labyrinth clearance should in all cases be filled with grease without
regard for the type of lubricant in the bearing (labyrinth closures are more fully
illustrated below).
Fig. 43
, ?
Fig. 44
. Felt seals may be employed if the peripheral speed of the shaft!, where it
contacts the seal, does not exceed 4 to 5 ni per sec for ground shafts and 7 to 8 m
per sec for polished shafts and high quality felt. At higher speeds, the friction of.
the felt on the shaft causes a high temperature which hardens the felt and decreases
the efficiency of the seal.
* In all the types of seals and closures described here, the shaft is considered as rotating -
in all cases.

Fig. 45 illustrates the more widely employed designs of closures in which
annular clearances and grooves are used as sealing member. This type of closure is
based on the creation of a small annular clearance, between the housing cover and
the shaft (Fig. 45a), filled with grease which prevents the entry of foreign matter
into the bearing.
Rbtary washers or flanges, due to the centrifugal force, throw off the oil or
foreign matter which gets on the washer. This type operates more efficiently than
the stationary type.
Rotary flanges and washers are the more reliable, the higher their peripheral
speed.
Stationary washers are employed, in the majority of cases, for bearings with
grease lubrication while rotary washers are used for any type of lubrication.
Oil slinger rings and grooves on shafts, have found wide application in
preventing the leakage of oil from bearings (Fig. 47).
Grease grooves are provided in the housing cover (and often on the shaft also)
to facilitate retaining the grease in the annular clearance (Figs. 45 b and 45 c).
This type of closure can be used in all cases when the bearing is lubricated
with grease and operates in comparatively clean surroundings.
The peripheral speed of the shaft is not limited for this type of closure. The
thinning-out temperature of the grease filling the annular clearances should be
higher than the working temperature of the bearing assembly to prevent it from
running out of the clearance.
Protective washers and flanges, most frequently met with in practice,
are shown in Fig. 46. Protective washers may be stationary (stamped "a" and
Oil, passing out of the bearing, runs on to the ring or into the groove and is
thrown by centrifugal force into a recess of the housing cover from where it drains
back into the bearing through a specially provided channel. Oil slinger rings can be
made integral with the shaft (Fig. 47a) or installed in a groove on the shaft
(Fig. 47 b). They may be of the single (Fig. 47 c) or double type (Fig. 47 d). These
devices provide the highest efficiency at high peripheral speeds and only in
assemblies lubricated with fluid lubricant (oil).
In cup seals, the sealing member is a cup of leather, rubber, plastics, etc.
which may be enclosed in a metal holder. The contact of the seal on the shaft is
provided either due to the elasticity of the cup (Fig. 48) or by the aid of an annular
turned "b") or rotary (stamped "c" and turned "d"). The sealing action of statiunary
? washers is negligible. Due to the narrow annular clearance between the washer
and the shaft, stationary washers mechanically prevent the lubricant from leaking
out and the entry of foreign matter into the bearing.
. Fig. 48
coil spring (garter' spring) (Fig. 49) w1ic4 passes the cup to the rotating shaft. If
the chief aim is the retention of 'the lubricant, the seal should be applied cupped
inward toward the bearing. If it is necessary to protect bearing from external, dirt,
it should be cupped in the. opposite direction. In cases, when both the above
requirements are present, a double seal is employed with the separate seals cupped
in both directions (Fig. 50).

For ordinary quality of finish of the friction surfaces of the shaft, the tileof
cup (leather) seals is permissible for peripheral speeds of the shaft not exceeding
6 to 7 m per sec. If the shaft has a fine finish, speeds up to 15 m per sec' Qy
be allowed.
Fig. 50
Fig. 51
This type of seal operates efficiently under the most difficult conditions with
either grease or oil as the lubricant.
Labyrinth closures (Fig. 51) operate very reliably under comparatively
difficult bearing operation conditions. The sealing action is based on the provisiOn
of a tortuous path of small clearance between the rotating and stationary members
of the closure. This path is sealed by a film of grease. This type of closure has the
following considerable advantages over felt and cup seals: low internal friction
of the lubricant, absence of members subject to wear, simple maintenance and
unlimited peripheral speeds of the shaft.
Labyrinth closures combined with other types of seals (felt seals, protective
washers, grease grooves, oil slingers, etc.) are the most reliable and effective of
all types of seals. In accordance with the design of the assembly, either axial
(Fig. 52) or radial (Fig. 53) labyrinth closures may be applied. In cases where
Fi.g. 52
`2311.
Fig. 53
temperature extensions of the shaft are possible, the use of axial labyrinth-closures
is excluded due to the possible contact between the rotary and stationary members
of the closure.
Labyrinth closures operate equally effectively for both grease, and oil
.lubricants. In either case, the labyrinth paths should be filled with grease,

Not one of the above sealing devices or closures can be considered as a uni-
versal type. Consequently, in engineering practice and especially for difficult
operating conditions, a combination arrangement is often employed comprising
the above described main elements suitably selected to provide the highest
efficiency in operation.
Recommended dimensions for some types of seals and closures, for normal
operating conditions, are given in Table 42.

3. SELECTION OF LUBRICANTS FOR ANTIFRICTION BEARINGS
Either oil or grease may be used for antifriction bearing lubrication, the
choice depending on the operating conditions and design of the equipment to which
the bearings are applied.
Fluid lubricants ? oils are the most efficient bearing lubricants but elaborate
oiling devices and closures are frequently required to provide the necessary
hermetic properties.
When selecting a grade of oil, it is necessary to take into consideration the
load, speed and operating temperature of the bearing. The higher the load and
temperature, the higher the Viscosity of the oil should be. Por small loads, low
temperatures and high speeds low viscoOfy oils are used.
A list of mineral oils, which can be used for lubricating ball and roller
bearings, are given below.

Animal and vegetable oils, in their pure form, are not recommended for
lubricating ball and roller bearings as they contain' a large amount of organic
acids which may cause corrosion in the operation of the bearing. Besides this, such
oils have a tendency to change their chemical and physical properties during
operation and especially at the high temperatures and churning that take place
in bearings.
4. METHODS FOR APPLYING OIL TO BEARINGS
Oil can be applied to ball and roller bearings in the following manner: 1) From
drop feed oil cups when a definite supply of oil to the bearing is required (a few
drops per minute) ;2) By means of wick lubricators, when the bearings are mounted

ke,
on vertical shafts; 3) By means of an oil reservoir with the balls or rollers dipping
into the oil or by splash feed from other members dipping into a common reservoir'4,
with the bearings and 4) By a circulatory system.
When a bearing is lubricated by dipping into an oil reservoir, the oil level:,
should not exceed the axis of the lower ball or roller for speeds up to 3000 r. p.
At speeds over 3000 r. p. m. the oil should just reach the lower ball or roller. .
It is necessary to be very careful when designing a method for applYing oil to.
bearings operating at high speeds. Such bearings require a constant supply of oil
in small amounts for ordinary operating temperatures (70?-800 C) and increased
quantities (up to 3 litres per min) when it is necessary to dissipate heat from a
bearing which overheats. In the latter case, it is better to feed the oil by means of
pressure spraying or .as an oil mist created by mixing the oil in a definite propor-
tions with dry compressed air.
As oils are liquids, suitable seals must be provided to prevent their leakage ,
from the housing. This matter must be given special attention. In cases where the
operating conditions and the design allow the use of felt seals, the. felt should be
cleaned of dust, dirt and other abrasive substances before cutting out the rings.
The edges of rings should be cut off evenly. Before installing the felt seals in the
retaining grooves, they should be dehydrated and impregnated with mineral oil.
The latter is accomplished by immersing them in an oil bath at a temperature of
105?-110? C for 25 to 30 min. The same oil is used for impregnating the rings as for
lubricating the bearings during operation.
Recently, oil-resistant rubber (sevanit) seals have found wide application.
They properly prevent oil leakage from the bearing housing and protect it from
the entry of foreign matter, dust and dirt.
5. GREASE LUBRICATION
Greases are plastic colloidal systems which retain their form at normal temper-
atures (20? to 30? C) but easily change it by the action of small external forces.
Greases form a plastic seal between the shafts and housings of bearings to
prevent the entry of abrasives and dirt to the working surfaces of the bearing.
This is of utmost importance when the bearing housing is surrounded by an atmo-
sphere containing much dust and dirt.
In composition, greases are complex formations consisting chiefly of mineral
oil and a thickener.
The most widely used greases have soaps, that is, the salts of natural or
synthetic fatty acids, as thickeners.
Commercial greases are produced with either calcium, mixed calcium and
sodium, sodium, aluminiuth, lithium, lead or other soap bases.
In accordance with the soap base of the grease, the latter possesses specific
properties.
Calcium soap greases (fatty solid 'oil 31, M and T according to GOST 1033-41)
98 STAN KOIM PORT le
have a melting point below 9.0? C. They are practically not water soluble and conse-
quently moisture resistant. They can be used for excessive moisture conditions
when the operating temperature of the bearing does not exceed 55?-60? C. Calcium
soap greases, which contain water as a necessary structural element, cannot
operate for lengthy periods of. time at temperatures of 55?-60? C and especially
above .this temperature. At this temperature the structurally combined water is
evaporated. In this case the grease separates into its constituents,"the more liquid
components leak out through the housing clearances and the soap densifies, often
to a hard black deposit.
Sodium soap greases; Konstalin YT-1. (GOST 1957-53), Konstalin CK-Y TC-1
(GOST 5703-51) and grease KB-YTM (GOST 2931-51) are produbed, as a rule, of
refined mineral oils and sodium soap. These greases are very sensitive to Moisture.
When mixed with water, they form an emulsion of the oil-water type that is
washed off the working surfaces of the bearing. For this reason sodium soap
greases should be used when the bearing operates in dry surroundings.
Sodium base greases have a higher melting point than calcium greases. The
melting point, of sodium base greases varies with the various grades, but May be
as high as 175? C.
Sodium soap greases ard very stable. They possess' the property of being
solidified again into grease upon being cooled after having been melted. At this.,
they do not lose their lubricating properties.
Mixed calcium and sodium soap greases, No. 1-13 YTB (GOST 1631-52) and
1411 1 (GOST 3257-53), contain a predominant quantityof calcium soap.This renders
them less sensitive to moisture than sodium base greases and they may be used in
the presence of excessive moisture.
Grease No. 1-13 may be used at working temperatures up to 80? C and grease
Hill (for rolling mills) may be used at working temperatures up to 60? C.
The oil industry produces a number of greases for special purposes.
Grease Tsiatim 201 ? YTBM-1 (Spec. 326-50) is used for lubricating small
size bearings operating in a wide range of temperatures above and below 0? C.
This grease is also used for completely sealed (double seal) bearings. These
bearings are lubricated during assembly at the Works and the lubricant cannot
be changed or replenished during operation. Completely sealed bearings must
not, under any circumstances, be washed in gasoline (petrol) or kerosene.
When greases are used as bearing lubricants, leakage can be prevented
without the ilse of elaborate seals, the bearing -will operate for considerable periods
without changing the lubricant and the bearing is effectively Protected against the
entrance of foreign materials from the surroundings.
Greases are not recommended in cases where special requirements are made
concerning minimum friction during operation.

The amount of grease that should be applied into the housing must be
determined from practical consideration in each actual case.
An excessive amount of grease in the bearing always causes a rise in working
temperature., Therefore, if a suitable amount of grease is supplied to the bearing
and one is certain of its proper quality, an additional amount of grease should not
be added in the housing if a sharp rise in temperature is noted during operation.
Instead of this, the reason for the high temperature must be found out and
eliminated.
A slight rise in temperature may always be possible when beginning operation
with a new bearing. Under norinal operating conditions, however, the temperature
should fall after a few hours and remain stable during subsequent operation.

STORAGE AND RENEWAL OF PACKING AND ?CORROSION
PREVENTING OF .BEARINGS
The main cause of damages to bearings, before they are mounted, is corrosion.
Even the very slightest darkening or traces of corrosion on bearing races,
balls or rollers will result in premature destruction of the bearing. The rules for
handling bearings in storage must be strictly followed to maintain them in a proper
condition.rotection against corrosion, the surfaces of the bearing are coated with
As a
p
an uninterrupted layer of anti-corrosive lubricant (slush).
Common grease YH3 (GOST 3005-51) or petrolatum YH (GOST 782-53) is
used as this anti-corrosive lubricant. If bearings have been properly packed and
stored, these lubricants can reliably protect bearings from corrosion for a period
of 12 months. To maintain bearings in a proper condition, they must be inspected
periodically and re'packed after from 9 to 12 months of storage. Repacking of
bearings provides for:
cleaning of bearings to remove the old lubricant;
coating of the bearings with a fresh layer of lubricant;
packing of the lubricated bearings.
When washing the bearings before repacking, besides removing the old
lubricant, all of the surfaces should be carefully cleaned of dirt which may have
entered the bearing through damaged packing.
Depending on the quantity of bearings, undergoing repacking, and the
available equipment; bearings may be washed in gasoline (petrol), hot mineral oil
or emulsions (solvents).
1. WASHING OF BEARINGS IN GASOLINE (PETROL)
An adequate quantity of gasoline and 6 to Pk (by volume to gasoline) light
mineral oil, as for instance industrial oil "12" or "20" (GOST 1707-51) are poured
into a clean bucket or tank. To remove the old lubricant, the bearing (medium and
small sizes) is immersed in the gasoline, the inner ring is held while the outer
ring is slowly rotated until the retainer, races and rolling elements are cleaned
of grease.
If the bearing is very dirty, it should be cleaned in gasoline, without rotation,
until the most part of the dirt is removed. This prevents the hard particles of dirt
from damaging the polished working surfaces of the bearing.

' 'if- a large number of bearings are to be cleaned at the same time, it is
necessary to provide iwo baths, one for preliminary and the other for finish
washing.
When the bearing is clean, it is removed from the tank, the gasoline is allowed
to run off and it is placed to dry on a bench covered with alean paper.
2. WASHING IN HOT MINERAL OIL
This method of washing bearings has found wide application. It is especially
convenient to wash large sized bearings with hot oil.
In this method, the bearings are washed in metal baths heated by electricity
or steam. The dimensions of the bath depend on the quantities and sizes of
bearings to be washed. A metal electrically-heated bath of welded design with
a cover and thermometer is shown on Fig. 55.
A grating, on which the bearings are placed, is arranged at a distance of
50-70 mm above the bottom. This prevents -the bearings from contacting the
highly heated bottom and the -settled dirt.
Fig. 55
Washing is carried out by lowering the bearings on metal hooks into the bath
containing clean mineral oil (industrial oil "12" or "20"), heated to 95?-100? C for
from 5 to 20 min. During immersion in the oil, the bearings are shaken a few
times.
As the bearings become heated, their protective grease melts and mixes with
the heating oil. After washing, the bearings are removed from the bath and placed
on a clean pan to allow the oil to drain off.
Very dirty bearings should be cleaned in tw,o baths providing a preliminary
and finish wash.
For washing a large .number of small bearings in hot oil, it is convenient to
use special baskets 'made of wire screen. The basket containing the bea.rings is
immersed into the hot oil bath and shaken to facilitate the washing.
102 ? S TAN KOIMPORT
3. WASHING IN A WATER SOAP SOLUTION
When repacking large lots of bearings, to economize oil and gasoline, they
can be washed preliminarily in a 2-2.5% aqueous olein-potassium or olein-
sodium soap solution, at a temperature of 750 to 95? C followed by Obligatory
subsequent washing in hot oil.
Soaps made of vegetable oils or fatty acids may also be used.
During washing, the bearings are hung on hooks or arranged in baskets, immersed
into the bath and shaken to speed up the washing.
The washed bearings are hung above the bath so that the excess soap solution
drains off and then carried to the second bath.
In the second bath, the bearings are washed in "industrial oil 12 or 20" or
"turbine oil 22" (GOST 32-53) at a temperature frbm 90? to 100? C.
lithe bearings are to be inspected, they should be washed in gasoline after
havir.g been washed in the second bath and cooled.
4. SLUSHING OF THE BEARINGS
Bearings, washed by means of one of the above methods, should be
subsequently washed in a bath of cannon grease at a temperature from 1100 to
120? C to completely remove all moisture.
After the grease has drained off and the bearings have cooled to some extent,
they are carried to another bath containing cannon. grease at a temperature from
60? to 70? C or petrolatum at a temperature from 550 to 60? C.
Immersion for a short time (20-30 sec) in this bath coats the bearings with
a layer of anti-corrosive grease.
5. REPACKING OF THE BEARINGS
1. After washing and slushing of the bearings they are placed on metal pans
until the grease solidifies.
2. The cooled bearings are wrapped in moisture proof paper and placed in
cartons, boxes or on the shelf.
3. During reslushing and packing, bearings should not be touched by bare
hands as corrosion may appear at the places touched due to the perspiration on
the hands. Bearings should be handled by means of oiled paper or metal hooks.
The grease, paper and auxiliary tools should be clean. -
6. STORAGE ROOMS
Rooms for the storage of bearings should be clean, dry and isolated from
dust, acid.fumes and other volatile matter which may cause corrosion. The storage
room should be suitably equipped, have central heating and ventilation and be

provided with the necessary fire 'prevention measures. The air temperature in the
room should be constant and in the range from 5? to 25? C.
It is not. advisable to store bearings at lower temperatures as the grease
may crystallize and cracks may appear in the grease coating through which
moisture might penetrate and cause corrosion.
On the other hand, the temperature should not be high enough to melt the
grease and allow it to ,run off the bearing surfaces. The daily fluctuation in
temperature should not exceed 5? C.
Sharp fluctuations in temperature in a short period of time are not
permissible as the bearings may "sweat" and be subject to corrosion.
The relative humidity should not exceed 700/0.
The conditions under which bearings are being stored should be systematically
checked.
The area of the storage room depends upon the number and sizes of bearings
in storage.
Centralized warehouses for the storage of large lots of bearings should
satisfy the stipulations of fire prevention regulations and comprise:
a) a vestibule,
b) a separate room for the -servicing personnel,
c) an isolated room for repacking Of bearings,
d) a room for storing of bearings on shelves or in boxes.

MOUNTING AND DISMANTLING OF . ?
BALL AND ROLLER BEARINGS ?
Years of experience in the application of antifriction, bearings have shown
that improper mounting is one of the main reasons for premature failure of
bearings in operation. It is consequently imperious that each maintenance man
should know and follow the chief mounting rules for ball and roller bearings.
indicated below.
1. PREPARING OF BEARING SEATS FOR MOUNTING
The bearing seats should have a carefully machined cylindrical surface with
dimensions corresponding strictly to those indicated in the shop drawings.
The presence of dents, traces of corrosion, metal chips and abrasive particles
on the bearing seats make bearing mounting very difficult and in some cases,
impossible.'
. Before mounting, it is necessary to examine carefully the bearing seats on the
shaft and in the housing, faces of the shoulders, fillet radii and machine parts
associated with the bearings (flanges, spacers, sleeves, etc.).
a) Dents, burrs and corrosion spots discovered on the bearing seats should
be carefully removed.
Dents and burrs are removed with a smooth file and then the file scratches
are eliminated with fine emery cloth No. 000.
b) All lubricating channels in the shaft and housing should be checked,
cleaned out and blown through with compressed air.
c) After eliminating the machining defects, the bearing seats and machine
parts associated with the bearings should be cleaned of chips, sawdust and sand,
washed with kerosene, wiped dry with clean rags and inspected to check whether
the dimensions correspond to those on the shop drawings.
d) Bearing seats and associated machine parts that are incorrectly machined,
that have taper and out-of-roundness exceeding the tolerances and a poor finish
must not be accepted for mounting.
Inspection must be carried out with gauges and tools of the proper accuracy:
e) Parts of bearing assemblies in which the noted defects have not been
eliminated should not be accepted for mounting.
All properly machined bearing seats in the housings- and on the shafts, as
well, as the parts associated with the bearings should be coated before. assembly
with a thin layer of oil and be protected. from dirt.

2. 1-IAN DUNG OF ANTIFRICTION BEARINGS BEFORE MOUNTING
a) The bearing should not be taken out of its packing nor should the
protective grease be washed .off until just before mounting. It should then be
.unpacked and.washed in gasoline or hot mineral oil.
The washing of the bearings may be omitted. if the packing is undamaged
and the grease has not hardened.
b) To avoid dirt in the bearing, it should not be placed directly on the bench
after unpacking. If necessary, it should be placed on a piece of clean paper.
c) To avoid corrosion, the washed bearing should not be held in the bare
hand. Clean paper or cloth should be used for this purpose.
The use of bearings as gauges for machining bearing seats is not recommended.
Only universal measuring tools or gauges should be used.
3. MOUNTING OF BEARINGS
a) Bearings should be mounted on shafts by means of a mounting sleeve (soft
metal tubing) and a hydraulic or screw press, a mounting sleeve and a hammer
or by means of special mounting devices.
?
? The use of a press in mounting antifriction bearings is strongly recommended,
as its use ensures a smooth, shockless pressure on the mounted bearing and there
is no danger of damaging associated parts (seals and oil catcher washers). For
small sized shafts, mounting bearings with a press can be carried out by two
methods: either the shaft is set up stationary and the bearing is pressed on it or
the shaft is pressed into the stationary bearing.
Pressing a bearing on a shaft by means of a press and mounting tube is shown
in Fig. 56.
If the shaft is pressed into the shaft, the inner ring of the bearing should be
set up on a face block having a hole slightly larger than the bearing bore (Fig. 57).
Special care must be taken to align the shaft and bearing properly as other-
wise the mounting will be difficult and the ground surface of the shaft will be
burred or distorted. In some cases the inner ring of the bearing may be ruptured.
The pressing force should be applied only to the bearing ring that is being
mounted with an interference fit. This force should not be transmitted through
the balls or rollers.
If a press is not available or cannot be used; the most efficient method for
mounting bearings is by means of a mounting tube with. a plug (Fig. 58) and a
hammer. .
The sphe'rical form of the plug ensures a more proper distribution .of the
pressing force on the face surface of the ring.
106 ? S TAN .K 0 I PORT-
A flange is welded to the mounting tube to protect the bearing from particles
of metal' and dirt which may fall on the bearing from the tube walls and plug
during the hammer blows. -
The inside diameter of the tube should be slightly larger than the seat on the
shaft and the end should be carefully squared.
Fig. 56
Fig. 57
Fig. 58
To facilitate mounting bearings on shafts it is advisable to heat them in hot
mineral oil. The oil temperature should not exceed 100? C.
b) lithe bearing is mounted with an interference fit in the housing (and a
clearance fit on the shaft), the above mounting methods may be used. In most
cases, special mounting tubes or arbors, similar to those used for mounting
bearings on shafts but with suitable dimensions, are used for pressing bearings
into housings.
c) When it is necessary to mount the bearing with an interference fit both on
the shaft and in the housing, a flange is welded to the open end of the tube to
apply the force simultaneously to both rings of the bearing (Fig. 59). In other
cases, a special solid arbor is used.
To facilitate mounting and to prevent damage to bearing seats when the
outer rings of bearings are mounted into housings with drive fits, the housings, in
some cases, are heated to a temperature of 100? C in an oil bath or (for large sizes)
in a muffle furnace.
d) When mounting the bearing, care must be taken to fit it tight against the
shoulder face without any clearance: To ensure such a fit the bearing should be
driven, with a hammer throtigh the mounting tube, firmly against the shoulder
while the bearing is cooling.
e) For proper operation of all bearings and especially- those which are not
self-aligning, the axes of the shaft and housing must coincide precisely. If the

axes do not coincide, the rolling elements may be overloaded due to their
jamming (Fig. 60). This will cause premature failure of the bearing. For this.
reason, the bearing seats should be accurately aligned before mounting.
f) As a result of improper machining of the bearing seats in split housings, a
clearance may appear between the halves of the housing when the bearing is
installed (before tightening the housing cOver bolts) as illustrated in Fig. 61. Upon
tightening the bolts, the outside ring of the bearing will be distorted and the
'rolling elements (balls or rollers) will be clamped between the bearing rings in
two opposite zones. Such a bearing is subject to premature failure in operation.
Consequently, housings with this defect should be corrected.

temperature does not exceed the ambient temperature by more than 60? C and
the actual temperature does not exceed 90? C. An excessive temperature may
draw the temper of the bearing elements and sharply decrease its life.
In all cases, when defects are discovered, the tests should be interrupted and
the reasons for the defects discovered and eliminated. Only after this may the
assenibly be considered as completed.
Fig. 59
g) It is very important in finishing the mounting of bearing assemblies in
which adjustable (radial-thrust or thrust ball and roller) bearings are installed,
to properly adjust the axial clearance of the bearings.
This axial clearance adjustment should be carried out with extreme care.
Not only the bearing life and normal operation of the mechanism, but also the
quality of the workpiece machined will depend on this adjustment if the bearings
are installed in such assemblies as, for instance, machine tool spindles.
h) After mounting the shaft with bearings in the housing and assembly of
parts associated with the bearings, it is necessary to check whether rotating parts
clear stationary parts (washers, covers, spacers, lubricating devices, etc.) and
whether oil is properly supplied to the bearings.
It is necessary to check carefully the assembly of sealing devices and
especially the clearances in labyrinth closures.
i) Before the test run, the mechanism should be turned over by hand if
possible. The bearings should run easily without jolts or jamming. If it is difficult
to rotate the mounted bearings, the reason causing this abnormal condition should
be ascertained and eliminated.
The temperature of the bearings and the running noise should be noted
during the test run. A sounding tube or rod or even a screwdriver is held to the

4. DISMANTLING OF BALL AND ROLLER BEARINGS
Bearings should be removed without damaging them or other associated parts
of the assembly. The possibility of fulfilling this requirement depends a great
deal on the designed form and dimensions of the bearing assembly parts. This
should be taken into consideration when designing the assembly.
Fig. 62 Fig. 63 Fig. 64
The removal of bearings, mounted on a shaft or in a housing with an
interference fit, should, as, a rule, be carried out by means of a press,. and screw
or hydraulic pulling tools. ?

An example of removing a bearing from a shaft by means of a vertical- press;
is illustrated in Fig. 62. '
In this case, the two bearing rings are set up with their faces supported on
two flat pads of the same thickness. The shaft is then pressed downward, out of
the inner ring of the bearing.
Fig. 63 illustrates a screw-type pulling device with two tie rods.
The tie rods should not deform during operation.
An annular recess or slots are provided on the seating shoulder of the shaft
to accommodate the lugs or claws of the pulling device.
In some cases bolts are used, instead of the tie rods with lugs, (Fig. 64)
together with demounting 'rings or semi-rings.
A universal pulling device with three tie rods is shown in Fig. 65.

Fig. 66
When bearings are removed from housings, a press or pulling device is also
used but they are somewhat different in design.
Fig. 66 illustrates a method for pressing the outer ring of a taper roller
bearing out of a housing by means of washers and a bolt with a nut.
To facilitate the removal of bearings, mounted on shafts with interference
fits, and to avoid damaging the bearing seats, the bearings are heated by mineral
oil at a temperature from 90? to 100? C.
When heating the bearing it is necessary to take care that the hot oil is
applied to the inner ring of the bearing and not to the shaft. It is convenient to
pour the oil on the bearing from some vessel having the form of a watering-pot.
The part of the shaft, on which the hot oil may accidentally be poured,
should be covered with asbestos or cardboard. This measure will decrease the
heating of the shaft and allow a larger temperature difference to be created
between the bearing ring and shaft.
110? STAN KOIMPORT ?
To detect the moment more certainly, when the bearing fit on the shaft has
loosened to the maximum extent, it is advisable to apply the pulling device to
the bearing with a preliminary load before beginning to pour the hot oil on the
bearing. When the fit has loosened properly, the elastic forces of the stressed parts
oi the pulling device will begin to pull the bearing.
5. BEARING MAINTENANCE DURING OPERATION
Antifriction bearings demand proper care during the operation of the
machines in which they are installed. Besides this, bearing assemblies of machines
should be systematically inspected.
The assemblies are checked by an external examination and a sound
inspection of the bearings in operaticin.
Defects, most frequently met with in bearing operation, include the
following:
a) Excessive temperature of the bearing assembly;
b) Abnormal noise or shock during operation;
c) Throwing of lubricant out of the housing.
Bearing overheating. may be caused by:
a) The presence in bearings of dirt or grit which has entered during mounting
or in operation;
b) Either excess or lack of lubricant in bearing;
c) The friction of parts associated with the bearing (labyrinth closures, seals,
washers, nuts, etc.);
d) Improper bearing mounting;
e) Improper application of the bearing;
f) Excessive wear or failure of the bearing elements.
Abnormal noise as well as overheating during bearing operation may be the
result of dirt in the bearing, damage to the working surfaces or interference
between the retainer and parts associated with the bearing.
Rhythmic knocks heard in a bearing may be the result of crumbling of
raceways or bearing rolling elements. They may also be the result of defects in
the meshing of gears or other assemblies of the machine.
Lubricant may be thrown out of the bearing as a result of wear, inefficient
sealing devices or excess of lubricant. This Is easily disceyned by leaks and spots
of lubricant on the 'housing.
. Besides the external inspection, attention must be paid to add and change the
lubricant in the bearing systematically. In the absence' of a centralized lubricating

system, lubricant should be added to and changed in the bearings in accordanc'e
with a schedule, compiled beforehand and taking into consideration the operatini
conditions and the type and grade of lubricant used. A timely addition of lubricant
is especially important for bearings operating at high speed.
Detailed inspection is carried out as a measure of preventative maintenance,
in definite periods of time, without regard for the actual condition of the bearing
assembly.
During detailed inspection the bearing, assembly must be opened to determine
the condition of the bearing, the possibility of further operation, as well as the
proper condition of the sealing and lubricating devices and the parts associated
with the bearing. The periods between detailed inspection should be determined
to suit the operating conditions, the intensity of operation of the bearing assembly
and it? degree of importance in the operation of the machine as a whole. -
