Crane and excavator slewing bearing
Contact NowCrane and excavator slewing bearing is a rotational rolling-element 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. (To "slew" means to turn without change of place.)
Compared to other rolling-element bearings, slewing bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the Falkirk Wheel are 4 metres diameter and fit over a 3.5 metre axle.
All of our slewing bearings can be manufactured with internal gears, external gears or without gearing. Special gearing, such as helical and worm gears, are also available upon request. The seal concept is also configured for each individual case of use, and takes account of particular environmental conditions, such as particularly saline or dusty air. The bearings can also be coated for extra corrosion protection.
