Four-Point Contact Ball Excavator Slewing Ring Gear Bearing

  Slewing ring bearing(slewing ring),is a bearing that able to bear a large axial load,radial and overturning torque.Slewing bearings are generally accompanied with installing holes,inner gear,outside gear,lubricating hole and sealing device,which enable mainframe structure compact in design,guide reliable,and easy to maintain.

Slewing bearings are combination structure including non-gear,outside gear and four point contact ball bearings,double angular contact ball bearings.cross-cylindrical roller bearing and three rows cylindrical roller bearings and so on.In which,four point contact ball bearings have higher static load capacity,while corss-cylindrical roller bearings have higher dynamic load capacity.

Slewing bearing widely used in lifting machinery.excavate machinery,construction machinery,port machinery,ships machinery,as well as precision radar launchers and large rotary devices such as missile launcher.
