Thrust Ball Bearing Composition:
Thrust ball bearing is consists of three parts: seat ring, shaft washer and steel ball cage assembly.
The shaft ring matched with the shaft, and the housing ring matched with the housing.
Classifications:
According to the force, thrust ball bearings are divided into one-way thrust ball bearings and two-way thrust ball bearings.
One-way thrust ball bearings can bear one-way axial load.
Two-way thrust ball bearings can bear two-way axial load, in which the shaft ring and the shaft are matched. The mounting surface of the seat ring is a spherical bearing with self-aligning performance, which can reduce the influence of installation errors.
Thrust ball bearings can’t bear radial load, and limit speed is low.
