A slewing bearing is a rotational rolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. Compared to other rolling-element bearings, slewing ring bearings are thin in section and are often made in diameters of a meter or more. Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base. As a professional slewing rings supplier, we provide small and large swing bearing with high performance.

 

Crane Slewing Bearing Turning endlessly. Effer slewing ring system allows the crane to rotate continuously. For the transport of oil and electrical signal from the base to the moveable part, Effer makes use of an innovative and reliable rotary distribution system which does not set limits to the crane’s maneuvers in any way.

 

Rotation under control. Effer uses gear motors with various reduction stages. The operator can thereby adjust the crane rotation speed, and check the movement of the load on the hook in an extremely safe and precise manner.Very fast, very slow. The various reduction stages of the engine RpM result in maximum operating power even at minimum rotation speed.Strong in every sense. The Effer system ensures constant rotation power in any boom working position in relation to the truck.
