Product Description

Slewing drive is a new type of slewing product, usually called slewing ring, which is usually composed of worm, slewing ring, housing, motor and other components. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and overturning moments. Compared with traditional rotary products, the new slewing drive features easy installation, easy maintenance and a greater degree of installation space.

Slewing drive are widely used in PV,CPV,STP solar tracking systems and construction applications including truck cranes, manlifts, turntables, port machinery, modular vehicles, small wind power systems and satellite communications.
