Slewing bearings are a large bearing capable of withstanding integrated loads and can withstand large axial, radial and overturning moments.Rotary support, also known as turntable bearings, some people also called it: rotation support, swing support.English name are: slewing bearing, slewing ring bearing, turntable bearing, slewing ring
Rotary support in the real industry is widely used, is known as: "machine joints", between the two objects need to be relative to the rotary motion, but also need to bear axial force, radial force, tipping moment of the machinery Essential transmission parts necessary. With the rapid development of machinery industry, slewing support in the ship equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries have been widely used.

Generator bearings used for Wind bearing ,Steel and non-ferrous metal processing mill bearings ,Hoisting , Engineering machinery bearing,  Mining machinery USES bearing ,Agricultural machinery bearing , Oil mechanical bearing ,Excavator bearing ,Metallurgical equipment bearing  ,Medical instrument bearing ,  Paper machine bearing Casting machine bearing, etc.

The company has introduced internationally-advanced large equipment with a full assembly line production capacity from forging,heat treatment,machining process,tooth making and to finished product assembly.The model of the products covers various standards and nonstandard specification up to 5500mm.

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.

We are committed to team the talents, integrate industry resources, and strive to further develop into a great enterprise of machinery parts and equipment. We look forward to working with you to create a better future. 
High qualified material, Stronger loading capacity, Larger radial and axial force bearing ability. Exquisite technological standard.
We provide different size slewing ring for tower crane and give you the best choice.  
 

Coresun Drive makes the tilting moment torque testing to ensure the quality and safety factor on slewing bearing bearing.
Quality is the foundation of enterprise development.
