"Ideas In Motion" ™ Since 1984
Overview:
Thrust ball bearings typically consist of two or more races/rings and a complement of balls. The balls may be loose between the races but are more typically retained. The retainers used are defined by the intended use and may be composed of steel, bronze, ceramic or elastomeric elements.

 They can be supplied with or without radius ball grooves in the rings.
Thrust bearings should be used under purely axial loads.
