Slewing ringsAre large-sized bearings which can accommodate a combined load, i.e. Axial, 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 rings have proven effectiveness in the following applications: construction, mobile and tower cranes, shovel, digging-wheel excavators, revolving grabs and winches, graders, logging industry machines including feller bunchers, loaders, vehicles for waste removal, hydraulic grippers, axles and undercarriages, assembly and access platforms, robots, manipulators and positioners, machine tools, special equipment (rescue vehicles, aerials, feller bunchers and tunnel machines, drilling equipment, wind turbines and cleaning and bottle filling machines).

Combining compactness, accuracy, smooth operation with relative high rigidity, together with simple mounting and operation reliability are qualities that allow the use of these bearings in all industrial branches.
