Slewing bearing (slewing ring bearing) | DK-BEARING

Slewing bearing (slewing ring bearing) The slewing bearing is usually composed of worm, slewing bearing, housing, motor and other components. Since the core part adopts slewing bearing, it can bear axial force, radial force and tipping moment at the same time. There are many forms, but the structure is basically the same.
