slewing rings are large bearings capable of carrying a variety of moments. The rotation speed of the ring bearing is lower, and it is widely used. Construction machinery is the place where the slewing bearing begins to be applied, such as earth-rock-moving machinery, excavators, stackers and reclaimers, graders, etc. Engineering ships, etc. In addition to various construction machinery, Ring bearing are also expanding into more fields. At present, similar to port equipment, metallurgical equipment, drilling platform equipment, etc. are beginning to use ring bearing on a large scale and replace the original bearings. According to the specific use, the structure adopts different working methods, and the basic operations are roughly divided into:

The inner ring is fixed to achieve support, and the outer ring rotates.

The outer ring is fixed, the support function, and the inner ring rotates.
