Product Description

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 additon they often enable the elimination of many components necessary in the

classical bearing arrangement.
