Product details

Slewing ring is also called "slewing ring" because its shape is similar to a plate. Its diameter is usually 0.2 ~ 5m. It is a large bearing that can bear axial and radial loads and overturning moments. The slewing bearing is composed of installation hole, inner gear ring or outer gear ring, isolation block, cage, lubricating oil hole and sealing device, so it can make the design structure of the host compact, simple guidance and easy maintenance.

Characteristic of structure, performance and application:

The single row four point contact ball slewing bearing is composed of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four point, it can bear the axial force, radial force and the tilting moment at the same time.

It can be used for slewing conveyer, welding manipulator, light & medium duty crane, excavator, and other construction machinery.
