Thrust self-aligning roller bearing

Thrust bearings have rolling elements which primarily support the axial loads of rotating devices. Several styles of bearings are available in thrust configurations.

 

Whereas radial-load bearings locate ball or roller races on the opposing inner and outer bearing rings, most thrust bearings have raceways machined into the faces of mating rings. This arrangement supports a load that is parallel to the bearing axis, but offers little to no support for radial loads. Thrust bearings are also inadequate to handle moment loads.
