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 (https://www.slew-bearing.com/Three-Row-Roller-Slewing-Bearing-pl571823.html) 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.
