The installation and disassembly method of excavator bearings should be based on the structure, size and the nature of the coordination with excavator bearing components. The pressure of installation and disassembly should be directly added to the end face of the tight fitting excavator bearing, and the pressure can not be transferred through the excavator bearing rolling body, because it will cause indentation on the working surface of the excavator bearing, affect the normal work of the excavator bearing, and even damage the excavator bearing. The cage, sealing ring, dust cover and other parts of the excavator bearing are easy to deform, and the pressure of installing or disassembling the excavator bearing cannot be added to these parts.
