slewing ring application in engineering ship

Slewing ring bearing is widely used in engineering ship, especially in ship crane for slow-turning under heavy load.

In ship crane, slewing ring serves as a joint between the upper structure and the undercarriage, providing a means of 360-degree rotation. As the load situation for ship crane slewing ring is relatively larger, three row roller slewing ring can provide better performance comparing with other structure slewing ring. And required diameter of slewing ring is normally over 1 meter and with internal gear.
