SKF light series four point contact ball bearings

SKF light series four point contact ball bearings has flange cross-section on the ring that without gear teeth. This design enables slewing bearing undertake considerable axial/radial loads and tilting moment, but with more compact structure and lighter weight. SKF light series four point contact ball slewing bearing can provide flexible rotation and easy to install and conduct maintenance.

Applications: where don't take too high loads but require light weight of slewing rings.
