Slewing bearing with external gear

   A slewing bearing or slewing ring 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. (To "slew" means to turn without change of place.)

    Compared to other rolling-element bearings, slewing bearings are thin in section; Slewing bearings resemble oversize aircraft control surface bearings. Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.
