Ball And Roller Slewing Ring is a bearing with special structure that could bear integrated load like axle load, radial load and overturning load. It combines support, rotating, transmission, fixed, sealed, anti-corrosion Ball And Roller Slewing Ring and other functions into one unit. Widely used in lifting machinery, construction machinery, transmission machinery, mining and metallurgy machinery, medical equipment and radar, ship, wind power and other industries.

Slewing bearing is same as normal bearings, it assembly by rings and rollers. However, compare to normal bearings, slewing bearing has a lot of differences. Normally, slewing bearing has huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal SKF snl 517 Bearing circumstances, slewing bearing operating in a low speed, high load condition. Slewing bearing comes with mounting holes, lubricating holes and sealing device. It has compact stucture, convenience to guide rotate, simple installation and easy maintenance etc.
