Slewing ring bearing can perform oscillating (slewing) as well as rotating movements. They may be used without gears or with internal or external gears. Following the drawing of customers' design.

Slewing ring bearings can take moment load and radial load, besides take thrust loads; There are ball bearing, roller bearing and ball-roller bearing at type; There are single-row, double-row and three-row at structure. With teeth and without teeth on conduction(outer or inner ring); At dustproof and leak grease proof type, with airproof and without airproof. At mounting with flanged(outer or inner ring), with bolt hole and without flanged.
