Slewing rings are large-sized bearings which are able to accommodate a combined load, i.e. axial and radial loads and tilting moment. They usually have fixing holes, internal or external gear, lubrication holes and seals, which allow a compact and economical arrangement. They often enable elimination of many components necessary in the classical bearing arrangement.
Compactness, accuracy and smooth operation with relatively high rigidity, simple assembly, easy maintenance and reliable operation are qualities that allow continuous widening of the use of these bearings in all areas of industry.
 
At present, PSL, a. s. mainly produces four-point contact ball slewing rings and slewing rings with crossed cylindrical rollers.
