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.

Unlike ordinary bearings, slewing bearings generally have mounting holes, internal or external gears, lubricating oil holes and sealing devices, so that the main engine design structure is compact, easy to guide and easy to maintain. Slewing bearings are widely used in engineering machinery, aerial machinery, handling equipment, automation machinery, special vehicles, new energy equipment, ship equipment, lifting equipment, hoisting equipment and other fields.

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?

Slewing bearings made of different materials have their own characteristics and applicable fields. Choosing the right material is crucial to improving equipment performance and extending service life. When choosing the material of a slewing bearing, it is necessary to comprehensively consider factors such as the working environment, load requirements, speed requirements, etc., and choose a material with appropriate performance and cost-effectiveness to ensure the normal operation of the equipment and extend its service life.
