How does a slewing bearing work

Nowadays, slewing bearings are widely used in a variety of applications such as cranes, forest industry, public works and so on. As a manufacture which produces high quality slewing rings, it’s important for us to make you have a better command of slewing bearings. In this article, we will introduce you about how a slewing ring bearing works.

 

A slewing ring is a contained system of balls or rollers, caging, raceways, mounting provisions, and often, integral gearing as well. According to the definition of Wikipedia, 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. Under this condition, to "slew" means to turn without change of place.
