Single Direction Thrust Ball Bearing Pdf 51320 M

Thrust ball bearings are composed of a row of steel balls (with cage), a shaft washer (tightly fit with the shaft) and a race (there is a gap with the shaft but tightly fit with the bearing seat hole), the steel ball rotates between the shaft washer and the race.

Can only bear axial load in one direction, not radial load. Because the axial load is evenly distributed on each steel ball, the load capacity is relatively large; however, the temperature rise is relatively large during operation, and the allowable limit speed is relatively low.

Thrust ball bearings are separable bearings. According to their structure, they are divided into one-way thrust ball and two-way thrust ball bearings. One-way thrust ball bearings can bear axial loads in one direction, and two-way thrust ball bearings can bear axial loads in two directions. None of them can bear radial load. Thrust ball bearings also have a structure with a cushion. Because the mounting surface of the cushion is spherical, the bearing has self-aligning performance, which can reduce the influence of installation errors.

Thrust ball bearings are mainly used on parts that bear one side of axial load and low speed, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc.
