Excavator bearings include: excavator traveling bearings, excavator slewing bearings, excavator needle roller bearings, excavator gearbox bearings, excavator traveling motor bearings, excavator traveling drive bearings, excavator spherical bearings, excavator slewing support bearings and Inch non-standard bearings used on excavators.

The installation and disassembly methods of excavator bearings should be determined according to the structure and size of the excavator bearing and the matching properties with the excavator bearing components. The installation and disassembly pressure should be directly applied to the end face of the tight-fitting excavator bearing retaining ring. The pressure cannot be transmitted through the excavator bearing rolling elements, because this will cause indentations on the excavator bearing working surface and affect the normal operation of the excavator bearing. It may even damage the excavator bearings. The cage, sealing ring, dust cover and other parts of the excavator bearing are easily deformed, and the pressure of installing or disassembling the excavator bearing cannot be added to these parts.
