It features compact in design, light in weight, the balls contact with the circular raceway at four points

Characteristic of structure, performance and application:
The single-row four point contact ball slewing ring is composed of 2 seat rings
It features compact in design, light in weight, the balls contact with the circular raceway at four points, via which the axial force,radial force and resultant moment may be born simultaneously
It maybe used for slewing conveyors, welding operating consoles, light, medium duty cranes, excavators and engineering machines
