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

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

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. It is widely used in lifting equipment, such as wheeled crane, crawling crane, gantry crane, tower crane slewing bearing(http://www.sl Read More

The size of the slewing ring required is dependent on the demands made on its:Static and dynamic load carrying capacity.LifeOperational reliability Definition of static load carrying capacitySlewing rings that undergo rotary motion only infrequently, undergo slow swivel motion, rotate only slowly or Read More

The raceway tracks of a slewing ring are hardened,the process of hardening these has a beginning an a end as the hardening may not overlap there is a small gap where there is no hardening. That is the so called soft zone of the slewing ring. This position is marked on the outside of every slewing ri Read More
