Four-Point Contact Ball Slewing Bearing

The four-point contact ball slewing bearing is an industrial bearing which consists of two bearing rings including the inner race and outer race. It is designed in compact structure and light weight. The steel balls contact with the arc raceway at four points and they are separated by the isolated blocks for avoiding sliding friction. This design allows the rolling element bearing to bear the axial force, radial force and overturning force simultaneously.

This four point contact ball bearing is generally used for yaw system of wind turbine, light duty harbor crane, light and medium duty marine crane, ferris wheel, crawler crane, slewing conveyer, welding manipulator, excavator and other engineering machines.

As a specialized manufacturer of four point contact ball slewing bearing, we have abundant experience on optimizing, designing and making the product according to actual application or supplied pictures.
