Ceramic Self-aligning ball bearing
The outer ring has a spherical raceway and its center of curvature coincides with that of bearing;therefore,the axis of the inner ring,balls and cage can deflect to some extent around the bearing center.This type is recommended when the alignment of shaft and housing is difficult and when the shaft may bend.Since the contact angle is small,the axial load capacity is low.
Pressed steel cages are usually used.
