Introduction to the Slewing ring bearing

Slewing ring bearing is a kind of large bearing which can bear comprehensive load, and can bear large axial, radial load and overturning moment at the same time. Slewing bearings are generally equipped with mounting holes, internal or external gears, lubricating oil holes and sealing devices, thus making the design of the main engine compact, easy to guide and easy to maintain. 

Slewing ring bearing presence of tooth, tooth and tooth in the four-point contact ball bearing, double row angular contact ball bearing, crossed cylindrical roller bearing, crossed tapered roller bearing and three composite bearings, four row cylindrical roller series, including four-point contact ball bearing has high static load capacity, crossed cylindrical roller with high load capacity, preloaded can make crossed tapered roller bearing bearing has great support stiffness and the rotation accuracy, three rows of cylindrical roller bearing combination because of the increase to the bearing capacity of the bearing height, forces respectively by different raceway, so under the same stress distribution, the bearing can greatly reduce diameter, Thus, it is a high bearing capacity slewing bearing that makes the main engine more compact.
