Single Row Crossed Rollers Slewing Bearing (Standard Series HJ)

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.
