The Brief Description of Self-aligning Ball Bearings: 

Self-Aligning Ball Bearing is recommended when alignment of the shaft and housing is difficult and the 

shaft may flex. 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. 

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

 

Bearing Advantages

1)    low friction

2)    minimum lubrication

3)    wear resistant

4)    running in not required

5)    requires little attention

6)    dimensions relatively small

7)    no scraping required to fit shaft

8)    easy replacement
