Slewing Bearing

Abnormal noise problem of excavator slewing bearing

It is normal for the new slewing bearing to make a uniform sound of rolling steel balls when it is idling. It will disappear after a period of running-in after installation. If there is a loud sound or special noise, you should pay attention.

1. The mounting surface is uneven and the mounting bolts are loose

2. There is a foreign body in the slewing bearing

3. Abnormal noise caused by a problem with the grease

4. Raceway and rolling body are severely worn

Conclusion: you should not be careless when there is abnormal noise in the excavator slewing bearing, you must check and solve the fault in time.
