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.

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 (single) and C by 0.81 and C0 by 1.47 (duplex) 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.
