Slewing ring bearing is a kind of large bearing which can bear the combined load of large axial load, radial load and overturning moment at the same time.Generally, the swing bearing itself is equipped with mounting holes, lubricating oil and sealing devices, which can meet the different demands of various hosts working under various working conditions.On the other hand, the turntable bearing itself has the compact structure characteristics, easy to guide rotation, simple installation and easy maintenance, which is widely used in large slewing ring such as lifting transport machinery, extractors, construction machinery, port machinery, wind power generation, medical equipment, radar and missile launcher.
Swing ring usually consists of four parts, including inner ring, outer ring, rolling body and isolation block.As the core part adopts slewing bearing, it can bear axial force and radial force at the same time.It has many forms, but its structure is basically the same.
