As an important transmission component in construction, the slewing bearing provides strong support for the rotation and positioning of various heavy equipment and structures with its unique structure and excellent performance. It not only improves construction efficiency and safety, but also reduces labor costs and maintenance costs, providing important guarantees for the efficient, safe and precise conduct of modern construction.

Since the slewing bearing of the excavator generally works under high load conditions, and the working environment of the excavator is relatively harsh, the slewing bearing is prone to failure, and the most common is various abnormal noises. So what causes the abnormal noise? What should be done to troubleshoot?

What materials are slewing bearings made of?

The slewing bearing is a new type of mechanical component. It consists of inner and outer rings, rolling elements, etc. The slewing bearing is a large bearing that can withstand comprehensive loads. It can withstand large axial and radial loads and overturning moments at the same time.
