Three Row Roller Slewing Ring Bearing

Slewing bearings (slewing rings), is a bearing that able to bear axial load, radial load and overturning torque. Slewing bearing are generally accompanied with installing holes, inner gear, outside gear, lubricating hole and sealing devices, which enable mainframe structural compact in design, guide reliable, and easy to maintain.
Slewing bearings include non-gear, external gear, and internal gear with different type, and has single-row ball slewing bearings, double-row ball slewing bearings, cross- roller slewing bearings and three-row roller slewing bearings with different structure. In which, single-row ball bearings have higher static load capacity; while cross- roller bearings have higher dynamic load capacity.
Slewing bearing widely used in lifting machinery, excavate machinery, construction machinery, port machinery, ship machinery, as well as precision radar, missile launchers and large rotary device such as missile launcher.
