Plastic thrust ball bearings consist of a row of steel balls (with retainers), a shaft ring (tightly fitted with the shaft), and a seat ring (with clearance from the shaft and tightly fitted with the bearing seat hole). The steel balls rotate between the shaft ring and the seat ring. It can only withstand axial loads in one direction and cannot withstand radial loads.

Characteristics of plastic thrust ball bearings

1. It can only withstand axial loads in one direction and cannot withstand radial loads.

2. Thrust ball bearings cannot restrict the radial movement of the shaft or housing, but can restrict the axial movement of the shaft and housing in one direction.

3. During installation, the axis of the shaft and the housing hole must be kept concentric, otherwise premature bearing damage may occur due to stress concentration.

4. The axis centerline should be perpendicular to the support surface of the shell, and no tilting or bending of the axis is allowed.

Application of plastic thrust ball bearings:

Suitable for automobiles, machine tools, crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc.
