Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing , which can be caused, for example, by shaft deflection.Self-aligning ball bearings Designed to handle misalignment MRC self-aligning bearings have two rows of balls with a common sphered raceway in the outer ring. This gives the bearings their self-aligning property, permitting angular misalignment of the shaft relative to the housing.

The design of a self-aligning ball bearing incorporates a spherical outer raceway. This allows for misalignment, shaft deflection, and housing deformations, giving you a bearing that can work in potentially problematic applications.Self-aligning ball bearings generate less friction than other styles of bearings, which allows them to run at higher speeds without building up as much heat. As a result, self-aligning ball bearings are more suitable for low- to medium-sized loads.
