Single Row Slewing Bearing

The single row slewing ring bearing have two types: single-row four point contact ball slewing bearings and single row cross roller slewing ring. It features compact in design, light in weight, small in assembling clearance, and high in installing precision.

Double Row Slewing Bearing

The double row ball slewing bearing is suitable for the larger axial load, for its ability of high supporting capacity and reliability.

Three Row Roller Slewing Bearing

This series of slewing bearing is mainly made up of in-up ring, in-down ring and outside ring. Three rings are separated so each row roller loads can be confirmed exactly and they can bear axial force, resultant torque and considerable radial force at the same time. This series has the maximum load capacity of these four series. It features compact in design.
