Slewing ring bearings have unique load-bearing characteristics and are usually used in hoisting machinery, excavators, slewing tables, wind power generators, telescopes and tank turrets. Through the improvement of processing methods and the renewal of design concepts, slewing bearings can be applied to occasions with smaller dimensions, more complex structures and more precision.
Slewing bearings are widely used engineering ships and port equipment: dredgers, sand dredgers, ship loaders, ship unloaders
The slewing bearing is also called the slewing bearing, and some people also call it: rotating bearing, slewing bearing. The English names are: slewing bearing, slewing ring bearing, turntable bearing, slewing ring. Slewing bearings are widely used in the real industry. They are called “joints of machines”. They are mechanical places that require relative rotational movement between two objects, but also need to bear axial force, radial force, and tilting moment at the same time. An important transmission component necessary. With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, engineering machinery, light industry machinery, metallurgical machinery, machinery, industrial machinery and other industries.
Slewing ring can bear axial, radial load and tilting moment load simultaneously. It can be combined with pinion, planetary gearbox and motors…
