HS series slewing bearing
The single-row four-point contact ball slewing bearing is composed of two seat rings. It has a compact structure and light weight. The steel balls are in four-point contact with the arc raceway and can withstand axial force, radial force and overturning moment at the same time. Construction machinery such as rotary conveyors, welding operators, small and medium-sized cranes and excavators can all be used.
