Thrust ball bearings can withstand the design of the thrust load when running at a high speed, which is composed of a roller ditch with a ball rolling ditch. Because the sleeve is a seat cushion, the thrust ball bearings are divided into two types: flat -bottomed cushion type and tuning pad. In addition, this bearing can withstand the axial load, but cannot withstand the radial load.

Thrust ball bearings are only applicable to the parts with axial load and low speed, such as crane hooks, vertical pumps, vertical centrifugal machines, jack tops, low-speed reducers, etc. The axis, coil and rolling bodies of the bearing are separated and can be disassembled separately.
