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.
