[0002] Slewing bearing is a new type of mechanical component, which consists of inner and outer rings, rolling elements, etc. Slewing bearing is a large bearing that can withstand comprehensive loads. It can withstand large axial and radial loads and overturning moments at the same time. It has a compact structure, convenient guided rotation, easy installation and simple maintenance. Common slewing bearings are of three types: gearless, internally geared and externally geared.
