A slewing bearing or slewing ring turntable is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slow-oscillating load.Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.As for Read More

Slewing ring bearing is widely used in engineering ship, especially in ship crane for slow-turning under heavy load. In ship crane, slewing ring serves as a joint between the upper structure and the undercarriage, providing a means of 360-degree rotation. As the load situation for ship crane slewin Read More

A slewing bearing or slewing ring is a new type of mechanical component, which consists of inner and outer ring, rolling body and so on. The slewing bearing is a large bearing which can bear the comprehensive load. It can bear large axial, radial load and overturning moment at the same time. From th Read More

A solar tracking system positions various payloads―such as solar PV panels, reflectors or lenses―toward the sun. Trackers are used to maximize the amount of incoming light by following the sun as it moves across the sky. Solar trackers are categorized by the number and orientation of their axes and Read More

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 Read More

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 Read More
