We provide Ball type slewing rings and roller type slewing rings used in cranes.

Ball Type Slewing Rings: Featured in 4 point contact ball, one of the advanced structures in the world, This type of bearing is one of the ideal parts for the machines which needs a relative rotation and stand axial force, radial force and force of toppling movement at the same time between two rotating parts of the machines, such as  cranes, excavators, piling machines, and truck-mounted concrete pumps.

Roller Type Slewing Rings: With 3 seat seals, upper, lower and radial rollgangs separated, this type can sustain forces from different directions. The contact between rollers and rollgangs is linear contact, bearing great strength, thus they are the ideal fittings for heavy machines, and are usually applied to wheel cranes, truck cranes, excavators,  tower cranes and harbor loading cranes with heavy load.
