Slewing bearing is widely used in construction machinery, especially excavator. The feature of excavator turntable bearing(http://www.slew-bearing.com/Stock-internal-gear-ball-slewing-bearing-with-teeth-hardened-for-excavator-PC200-6-PC200-8-on-sale-pd6082760.html) is with hardened inner gear and th

A slewing bearing or slewing ring 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 t

A slewing ring(http://www.slew-bearing.com/Light-Slewing-Bearing.html) is a contained system of balls or rollers, caging, raceways, mounting provisions, and often, integral gearing as well. These large units are designed to transmit axial, radial, and tilting moment loads. And because they handle lo

What is slewing unit?The slewing unit comprises an upper part that usually rotates relative to a bottom part around an axis that is normally vertical. The slewing unit acts as both a connecting element and Bearing (pivot bearing). It must be able to withstand high axial forces.Application of slewing

The light slewing bearing has the same structure with four point contact ball slewing bearing, but the weight is light and could be used for some light type machinery applications. It could save some cost if the load capacity is low. The light duty slewing ring(http://www.slew-bearing.com/Light-Slew
