Ball slewing ring bearings for mobile cranes

THB Single row four point contact slewing ring is consisted of two rings (one inner ring and one outer ring.) It has compact structure and light weight. As its balls are four point contacted with the raceway, the slewing ring can take axial load, radial road, and tilting moment at the same time. It is used widely for the application of rotary welding machinery, medium and small series crane and excavators etc. Our slewing ring for the excavator slewing ring types will be updated from time to time.
