Model Number: Double Row Same Diameter Ball Slewi Brand Name: ZYS Key Specifications/Special Features: Slewing bearing is a large of 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 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 between 0.4m to 10m, and some even to 40m. Under normal 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 structure, convenience to guide rotate, simple installation and easy maintenance.Product: double row same diameter ball slewing bearingZYS double row ball slewing bearing is mainly made up of inside and outside rings. The diameters of up-row and down-row balls are the same. It is suitable for high precision mounting and capable to bear axial force, resultant torque and considerable large radial force.Double row ball slewing rings are widely application in wind turbine bearing (blade bearing/pitch bearing) and types of marine cranes.Three types of this kind of double row ball slewing bearings:A. Without gear bearing (non tooth)B. External gear bearing (external tooth)C. Internal gear bearing (internal tooth)ApplicationsZYSbearings are widely used in marine cranes, oil platforms, wind power installation platform, port cranes, pipe-laying vessels.
