Single-row Four Point Contact Ball Slewing Bearings


The single-row four point contact ball slewing ring is composed of 2 seat-rings. It features compact in design, and light in weight. The balls contact with the circular race at four points, via which the axial force, radial force and resultant moment may be born simultaneously. It may be used for slewing conveyers, welding arm and positioner, light, medium duty cranes, excavators and other engineering machines. 

Mainly applied area:

Four Point Contact Slewing Ring Bearing is widely used in many machines such as the rotary transfer machine, welding manipulator,small or middle size crane,excavator,and other construction machineries,etc.
