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.

As an important piece of equipment in construction machinery, the performance of the slewing bearing of the excavator directly affects the operating efficiency and stability of the excavator. During actual use, the excavator slewing bearing sometimes emits Abnormal noise not only affects the work effect, but may also cause damage to the equipment. Below, we will analyze the causes of abnormal noise in the excavator slewing bearing from several aspects.

What factors should be considered when selecting rolling bearings in actual use?

What impact does slewing bearing cleanliness have on bearings?

Do you understand the internal structure and application of slewing bearings?
