Light excavator slewing bearing 
The slewing bearing of a light excavator is easily damaged. Usually the replacement cycle is 2 to 3 years. In this case, the main bearing failure is the broken teeth of the slewing ring, abnormal noise when rotating or the slewing ring is stuck. When this happens, stop the operation immediately, otherwise the rotating motor may be damaged.

Objectively, it is unfair to put all the blame on the bearing quality, because the slewing ring of the light excavator has a large rotation radius. Overwork is sometimes required, causing the teeth to wear and eventually break. In addition, the operation method of the excavator driver will also affect the service life of the slewing bearing.

Slewing rings have high stiffness and load-carrying capacity, and we can provide customized types, such as tooth hardening, which can improve the wear resistance and service life of slewing rings. Special finishes or extreme environments are also available.
