CHARACTERISTIC OF STRUCTURE, PERFORMANCE AND APPLICATION

The single-row four point contact ball slewing ring is composed of two 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 may be used for slewing conveyers, welding operating consoles, light, medium duty cranes, excavators and other engineering machines.
