Four-point contact ball slewing bearing is composed of 2 seat-rings. It is compact in design and light in weight . The balls contact with the circular race at four points, which can support high dynamic loads , transmitting axial and radial forces simultaneously as well as the resulting tilting moments .
Four-point contact ball slewing bearing is composed of 2 seat-rings. It is compact in design and light in weight . The balls contact with the circular race at four points, which can support high dynamic loads , transmitting axial and radial forces simultaneously as well as the resulting tilting moments . It is mainly used for slewing conveyors , welding arm and positioner, medium duty cranes ,excavators and other engineering machines.
