Internal
Clearance
Axial internal clearance single
row angular contact ball
bearings
Internal clearance in a single row
angular contact ball bearing is only
obtained after mounting and is
dependent on adjustment against a
second bearing that provides axial
location in the opposite direction.

Bearings for universal pairing (suffix CB)
are the standard SKF bearings for paired
mounting in random order (back-to-back,
face-to-face or tandem). Bearings can be
supplied with smaller axial internal
clearance (suffix CA) or larger (suffix CC)
or with preload (suffixes GA, GB and
GC) for universal pairing.
Bearings identified by suffix CA, CB or
CC can be mounted immediately
adjacent to each other in any order and
two or more bearings may be used.
Bearings with preload of the GA, GB and
GC designs can only be arranged in
pairs, otherwise the preload will increase.

Radial clearance [~=] 0.85 axial clearance.
The values of axial internal clearance
for the classes CA, CB and CC can be
found in table 1. They are valid for
bearings arranged back-to-back or
face-to-face before mounting and under
zero measuring load. Preload values
for classes GA, GB and GC are given
in table 1a. Table 2 shows a
conversion from the old preload
suffixes to the current suffix.

Double row angular contact ball
bearings
Basic design bearings in the 32 A and
33 A series shown in the product table as
well as the corresponding sealed bearings
to 2Z and 2RS1 design are identical to the
corresponding bearings in the 52 and 53
series for the North American market. They
have the same performance characteristics
and dimensional features (except for the
width of size 5200). However, the sealed
bearings are filled with a different grease.
Bearings in the 52 and 53 series use a
mineral oil based high-temperature grease
with di-urea thickener. The operating
temperature range of this grease is -30 to
+175°C. The base oil viscosity is 115
mm2/s at 40°C and 12 mm2/s at 100°C.

For 3200 and 3300 series, the grease has
a lithium thickener with a mineral oil base.
The operating temperature is -30°C to
+120°C, with a base oil viscosity of
74mm2/s at 40°C

300-R Medium Series bearing bores range in
diameter from 12 mm to 280 mm. They are
used with heavy radial loads, one-directional
thrust loads, or a combination of both. They
can be furnished duplex ground for mounting
in pairs with two-directional thrust loads.

400-R and -RD Heavy Series bearings are available in bores
from 17 mm to 110 mm. They can handle very heavy radial
loads, one-directional thrust loads, or a combination of both.
Use duplex bearings for two-directional thrust loads.

1) Listed values are for pressed steel or polyamide cage, ABEC-1.
For phenolic composition cage, multiply by 1.66 for grease and 2.00 for oil. For machined bronze cage, multiply by 1.25 for grease and 1.50 for oil. For
phenolic composition cage, ABEC-5 or 7, multiply by 2.30 for grease and 2.80 for oil. The speed rating adjustment factors have been determined through
historical application and practice.
2) Rating for one million revolutions or 500 hours at 33 1/3 RPM.

MRC 7200 Light Series
(single bearings)
B
d 10 - 320 mm
d 0.3937 - 12.5984 in
The 7200 Series contains single-row angular contact bearings with a counterbored
outer ring. Bore sizes range from 10 mm to 320 mm, and most of these bearings
are available with a two-piece pressed steel cage, or a one-piece nonmetallic or
solid bronze cage. 7000 Series bearings are designed with an initial contact angle of
29 degrees, although some small sizes may have a lesser angle. 7200 Series
bearings can be used with moderate to heavy one-directional thrust loads, or
combined radial and thrust loads where the thrust load is predominant.
D
d
29° contact angle
Caution: Single bearings are not to be used where only radial loads are
present. For two-directional thrust loads, use duplex bearings.

1) For thrust rating multiply C by 1.32 and C0 by 2.94.
2) Listed values are for machined bronze cage, ABEC-1.
For phenolic composition cage, multiply by 1.33 for both grease and oil. For phenolic composition cage, ABEC-5 or 7, multiply by 1.86 for both grease and oil. For
pressed steel cage, ABEC-1, multiply by 0.67 for grease and 0.80 for oil. The speed rating adjustment factors have been determined through historical application
and practice.
3) Rating for one million revolutions or 500 hours at 33 1/3 RPM.

1) For thrust rating multiply C by 0.81 and C0 by 1.47.
2) Listed values are for machined bronze cage, ABEC-1.
For phenolic composition cage, multiply by 1.33 for both grease and oil. For phenolic composition cage, ABEC-5 or 7, multiply by 1.86 for both grease and
oil. For pressed steel cage, ABEC-1, multiply by 0.67 for grease and 0.80 for oil. The speed rating adjustment factors have been determined through
historical application and practice.
3) Rating for one million revolutions or 500 hours at 33 1/3 RPM.

MRC 7300 Medium Series
(Single bearings)
B
d 10 - 280 mm
d 0.3937 - 11.0236 in
7300 series bearings have the same ring and ball cage
construction as the 7200 Series but are heavier sectioned
bearings with a ball complement capable of handling heavier
loads. 7300 Series are listed with bore sizes from 10 mm to 280
mm. For two directional thrust loads, use duplex bearings.

29° contact angle
Caution: Single bearings are not to be used where only
radial loads are present. For two-direction thrust loads, use
duplex bearings.

2) Listed values are for machined bronze cage, ABEC-1.
For phenolic composition cage, multiply by 1.33 for both grease and oil. For phenolic composition cage, ABEC-5 or 7, multiply by 1.86 for both
grease and oil. For pressed steel cage, ABEC-1, multiply by 0.67 for grease and 0.80 for oil. The speed rating adjustment factors have been
determined through historical application and practice.
3) Rating for one million revolutions or 500 hours at 33 1/3 RPM.

7400 Series bearings are similar to the 7200 and 7300 Series but are
heavier sectioned and are used for heavy one-directional thrust loads or
combined radial and thrust loads where the thrust load is predominant.

"D" indicates a duplex ground half pair matched with an identical half pair and if
followed by an additional suffix letter to describe the type of duplex.
Note: ABEC 1 & 3 are stocked as half pairs where available.
Caution: Single bearings are not to be used where only radial loads are
present. For two-direction thrust loads, use duplex bearings.
Values for -D bearings are for back-to-back (DB) or face-toface (DF) mounting arrangements.
