Thrust ball bearings by the gasket-shaped raceway ring with raceway and ball and keep frame assembly composition, with the shaft with the raceway 

ring called as shaft circle, with the shell with the raceway ring called as seat circle. Bidirectional bearings will be the middle ring secret shaft with, one-way 

bearings can withstand one-way axial load, two-way bearings can withstand two-way axial load (both can not withstand radial load).
