Self-aligning ball bearings Self-Aligning Ball Bearings are ideal when the alignment of the shaft and housing is problematic and the shaft may bend. The outer ring has a spherical raceway with its center of curvature coinciding with the bearing. This allows the axis of the inner ring, balls and cage to deflect to some extent around the bearings center. The axial load capacity is low since the contact angle is small. Under normal loads, the permissible dynamic misalignment is approximately 0.07 to 0.12 radian (4 to 7 degrees).
