Slewing bearing,Slewing Drive is a new kind of rotary product. It is usually composed of worm, slewing ring, shell, motor and other components . As the core component uses slewing ring, so it can bear axial force ,radial force and tilting moment at the same time. This product can be widely used in heavy-duty flat-panel trucks, container cranes, Truck cranes, aerial vehicles, solar power generation systems, engineering machine and new energy and other areas.                This device is a rotary deceleration drive. It runs  through the motor (electric, hydraulic) drives worm and the worm driven by the slewing ring (worm). Thereby make an operation of the workpiece
