Should be based on the structure of the joint bearing, size and joint with the bearing parts of the nature of the fit. The pressure of installation and disassembly should be directly added to the end face of the tight fitting ring. The pressure can not be transmitted through the rolling body. This will cause indentation on the working surface of the joint bearing, affecting the normal operation of the joint bearing and even the bearing damage. Joint bearing cage, seals, dust cover and other parts easily deformed, the installation or removal of joint bearings can not be added to the pressure on these parts.
