Slewing Ring Bearing Definition:
Slewing bearings are large-sized bearings which can accommodate a combined load, i.e., radial loads and tilting moment. They are usually provided with holes for fixing bolts; internal, external or no gear; and lubrication holes and seals, which allow a compact and economical arrangement. In addition, they often enable the elimination of many components necessary in the classical bearing arrangement.
Slewing Ring Bearings are also called slewing rings, slewing bearings, slewing ring bearings, slewing gear, gear, turntable bearings and rotary bearing
