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 IMO Slewing Ring Bearing 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.

Depending on the application and type, large diameter IMO Slewing rings can be up to 6 meters in diameter and weigh more than 20 tons. They are used for various applications, including construction machinery, agriculture & forestry, tunneling & mining, ship building, conveyor & transportation systems, and medical technology. Additionally, IMO is a leading KOYO 6304 Bearing supplier of blade, yaw, and main bearings for an- and offshore wind turbines, and even provides balde bearings for tidal stream systems. Large-diameter anti-friction Slewing Rings designed to handle simultaneously occurring axial, radial and moment loads. The Slewing Rings can be combined with pinion, planetary gearboxes and motors which can be selected and acquired by the customer. Equipped with a sealed raceway system and an open gearing (if toothed)
