Single row four point contact slewing bearing
consists of two rings. compact structure and light weight.steel balls contact with circular rolling track on four points.

Single row four point contact ball slewing ring
use of internal radial preload forces can provide greater stiffness, and the strictly controlled radial and axial runout can provide accurate repeatability.

Single row four point contact ball slewing ring
light profile slewing rings feature rectangular cross sections, which allow for alternate hole patterns, improved stiffness, and the potential for more capacity.
Application
The slewing bearing is widely used in excavators, stacker and reaper, conveyors, cranes, robots, amusement equipment, military equipment, environmental protection equipment and medical equipment.
