What are the common faults of excavator slewing bearings

Excavator slewing bearings are critical components that support the weight of the upper structure and allow for the rotation of the excavator. Over time, they may develop faults that can affect the performance and safety of the excavator. Here are some common faults of excavator slewing bearings:

Wear and tear

The constant movement and heavy loads can cause the slewing bearing to wear and develop grooves, which can affect its performance and cause it to fail.


Exposure to moisture, dirt, and other contaminants can cause the slewing bearing to rust and corrode, which can affect its integrity and lead to failure.
