Slewing Bearing is a kind of large bearing that can withstand large axial load, radial load and overturning moment and other comprehensive loads. This type of bearing generally has mounting holes, lubricating oil holes, sealing devices, internal gears or external gears, so It can make the main engine compact, easy to rotate, easy to install and easy to maintain. The slewing bearing has Four-point Contact Ball Bearings without gear, external gear and internal gear, double disc Angular Contact Thrust ball bearings, crossed Cylindrical roller bearings, Crossed Tapered Roller Bearings and three-row cylindrical roller Combined bearings and other structural types. Four-point contact ball bearings have high static load capacity, crossed cylindrical roller bearings have high dynamic load capacity, and crossed tapered roller bearings have high dynamic load capacity. It has larger support rigidity and higher rotation accuracy.
