It is designed to withstand thrust loads during high-speed operation and consists of a washer-like ferrule with a raceway groove for ball rolling. Since the ferrule is cushion-shaped, thrust ball bearings are divided into two types: flat base cushion type and aligning spherical seat cushion type. In addition, this kind of bearing can bear axial load, but cannot bear radial load.
Purpose of thrust ball bearings: They are only suitable for parts that bear axial load on one side and have low rotational speeds, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc. The shaft ring, seat ring and rolling elements of the bearing are separated and can be assembled and disassembled separately.
