[0002] The slewing bearing is a new type of mechanical component, which consists of an inner ring, an outer ring, rolling elements, etc. The slewing bearing is a large bearing that can bear comprehensive loads and can simultaneously bear large axial, radial loads and overturning moments.

[0003] As a new type of mechanical component, the slewing bearing can bear large moments.

[0013] The beneficial effects of the present utility model are as follows:
