Our four point contact ball slewing bearing is made up of two seat rings. In this slewing bearing, the balls contact with the circular raceway at four points. The bearing can support axial force, radial force and resultant moment simultaneously.
Our four point contact ball slewing bearings are compact in design and light in weight. They can be applied in slewing conveyors, welding manipulators, middle or small sized cranes and excavators, etc.
