4-point contact slewing ring bearings inner gear

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 conveyor, welding manipulator, light & medium duty crane, excavator, and other construction machinery.

Selecting the appropriate slewing bearing can be a challenge, particularly if there are stringent technical, reliability or economic demands. In these cases, for example, XZWD application engineering service can provide advanced calculations and simulations utilizing state-of-the-art analyse methods to optimize and validate the best design to meet the customer requirements.

XZWD manufactures standard and customized slewing bearings in various designs with outside diameters from 0,2 to 5 m to meet the demands of particular applications.
