Abstract
A slewing bearing includes an inner annular body formed of unhardened stainless steel and coupleable with a fixed member and having an inner race with an unhardened race surface. An outer annular body is disposed about the inner body and is formed of unhardened stainless steel, is coupleable with a rotatable member, and has an outer bearing race with an unhardened race surface and a plurality of gear teeth engageable by a drive pinion to angularly displace the outer body. Rolling elements are disposed between and rotatably couple the inner and outer annular bodies. An annular seal is coupled with the outer annular body and has two opposing axial ends, an axial thickness defined between the ends, a sealing lip engageable with the inner body and an outside diameter and is sized such that the ratio of the outside diameter to the axial thickness is greater than fifty.
