The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. Pressed steel cages are usually used. Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.07 to 0.12 radian (4 to 7 degrees) under normal loads.

However, depending on the surrounding structure, such an angle may not be possible.


Suffix definitions of Self-aligning ball bearings:
C3: radial clearance than ordinary clearance

K: 1/12 taper tapered bore

K30: 1/30 taper tapered bore

M: Ball guided machined brass cage

2RS: with both ends of closures

TV: ball guide glass fiber reinforced polyamide (nylon) solid cage
