A slewing bearing or slew[ing] 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.

Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.

Light type slewing bearing is designed with compact structure, light weight and flexible rotation. Filling machine is using such slewing bearing is realize continuous and stable automatic filling.'
