Slewing Gear Bearing Arrangements

Construction equipment with revolving superstructures such as wheel loaders, cranes or excavators use slewing rings for revolving the lift mast and superstructure. These can have both internal and external gear teeth. Preloaded robust four point contact bearings have proved extremely reliable under high tilting loads and under very demanding operation. The bearings place only low demands on the adjacent construction.
