Excavator Bearings Introduction:
Excavator bearings include: excavator travel bearings, excavator slewing bearings, excavator needle bearings, excavator gearbox bearings, excavator travel motor bearings, excavator travel drive bearings, excavator joint bearings, excavator slewing support bearings and inch tapered roller bearings.
The installation and disassembly of the excavator bearing should be determined according to the structure and size of the excavator bearing and the nature of the matching with the excavator bearing components. The pressure for installation and disassembly should be directly applied to the end face of the tightly fitted excavator bearing retainer ring, and the pressure cannot be transmitted through the excavator bearing rolling elements. The retainer, seal ring, dust cover and other parts of the excavator bearing are easily deformed, and the pressure for installing or disassembling the excavator bearing cannot be added to these parts.
