Car ball cages are generally composed of bell shaped shells, three-way bearings or steel balls, dust covers, tie rings, and lubricating grease. When inspecting the car ball cage, the following aspects should be noted: internal and external spline and thread dimensions; Check the size of the oil seal of the outer ball cage, as there may be differences in the oil seal of different models of ball cages; Check if the internal spline groove is correct. The width of the groove will affect the movement of the ball cage on the half shaft after installation; The material and heat treatment performance require specialized equipment for inspection.
