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

The first step is the design phase of the slewing bearing.The first step is the design phase of the slewing bearing.Advanced calculation techniques attuned to slewing bearings guarantee an economic and safe dimensioning of load transmitting and of components in which deformation is a critical factor

Inner Ring and Outer Ring The bearings are comprised of two rings, each of which contains a precision raceway that is induction hardened on the surface to a specified depth. Each ring is made from a medium carbon steel forging.slewing bearings(http://www.slew-bearing.com/SLEWING-BEARING-pl502823.htm

The slewing arm davit is mainly used for lifting and lowering a boat/raft , and also for other types of raft davit. It have the functions of electrical(manual) hoisting, gravity lowering, hydraulic slewing (Oils fed from the pump station or accumulator/manual pump). It is provided with lowering an

Service Factors To determine if a Slewing Ring bearing is appropriate for an application, a SERVICE FACTOR is applied. Refer to the table below for a guide to the service factor to apply to your application. The load rating curves shown in this catalog are approximate, and represent an application s

China slewing bearing has been developing from a poor situation to sprung up across the country after more than 30 years development. Through the introduction of German Rothe Erde designing and manufacturing technology in 1985, Xuzhou slewing bearing factory was established, and the large bearing p
