If there is no professional inspection equipment, it is necessary to check the car ball cage mainly:

1. The size of internal and external splines and threads affects the loading size of the cage,

2. Check the size of the oil seal of the outer ball cage. Generally, the oil seal of different models is different,

3. Check whether the groove of internal spline circlip is correct. The width of the groove affects the movement of the cage on the axle shaft after loading;

4. Insert a shaft into the internal spline and swing the cage to see if it can rotate flexibly;

5. Materials, heat treatment performance, etc. need special equipment to check
