Self-aligning ball bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, inner rings with a cylindrical or tapered bore and ball and cage assemblies. The bearings are available in open and sealed versions.

Constructed with the inner ring and ball assembly contained within an outer ring which has a spherical raceway for self aligning this type of bearing is particularly suitable for applications where misalignment occurs from errors in mounting or from shaft deflection.

This type is often used in conjunction with Plummer Block Housings in blowers, fans and belt conveyors.
