Excavator bearings include: 

excavator travel bearings, excavator slewing bearings, excavator needle roller bearings, excavator gearbox bearings, excavator travel motor bearings, excavator travel drive bearings, excavator joint bearings, excavator slewing support bearings and Inch non-standard bearings used on excavators.

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