Ball bearing slewing rings

Ball bearing slewing rings by Liebherr are available in single- and double-row models, both with external or internal gear as well as without gearing. The ball bearing slewing rings are designed as four-point bearings which are characterised by four defined points of contact per rolling element, through which bilateral axial and radial forces and thus also a tilting moment can be transferred. Thanks to their simple construction, four-point bearings are an efficient solution for various applications with small to medium-sized loads.

Polymer spacers are conventionally used as intermediate pieces between the rolling elements, however there are bearing models with steel or brass cages.
