Overview

Self-aligning ball bearing

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 insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.

Key features

Accommodate static and dynamic misalignment
Excellent high-speed performance
Excellent light load performance
Low friction

Typical applications

Fans and blowers
Conveyor shafts
Textile machinery
Agricultural and general machinery

Selection guidance

Check expected misalignment, load, sealing needs, internal clearance, and available mounting space.
