Thrust ball bearing using high-speed operation can withstand thrust load design, with the ball rolling by roll gap shape ring gasket. Because the ring of the seat cushion, therefore, thrust ball bearing is divided into a flat base mat type and self-aligning spherical seat cushion type two kinds. In addition, this kind of bearings can withstand axial load, but can't bear radial load.

Thrust ball bearings use: apply only to bear a part of the axial load and low speed, such as crane hook, vertical pumps, vertical centrifuge, jack, low speed reducer, etc. The shaft of the bearing ring, race and rolling elements are separated, can wear &erosive respectively.
