Chinese Brand Rotating Bearing / Ball Mill Bearing
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.
