Slewing Bearing 
1. Introduction of Coresun slewing ring bearings
Coresun is a professional manufacturer in slewing ring bearings. We can also design and make other standard and non-standard ball slewing ring bearings, roller slewing bearings and precision slewing ring bearings as per customer's different technical requirements.
Slewing ring bearing is also called slewing ring, slewing bearing, turntable bearing, and rotary bearing. 
Slewing ring bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing ring bearings have their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions; 
On the other hand, slewing ring bearing itself has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily. 

2. Structure
2.1 Slewing ring bearings have different types as per different structures, here below is what we offering now: 
Single row ball slewing ring bearings 
Double row ball slewing ring bearings
Crossed roller slewing ring bearings 
Triple row roller slewing ring bearings 
Flange slewing ring bearings
2.2 The above slewing ring bearings can also be divided into three different types as per different transmissions:
Slewing ring bearings with no gear
Slewing ring bearings with external gear
Slewing ring bearings with internal gear

3. Features: 
Slewing ring bearings have more features: compact structure, reliable guide, simple installation, and easily maintenance
 
4. Application: 
Slewing ring bearings can be widely used in lifting & transport machinery, mining machinery, construction machinery, port hoisting machinery, port oil transfer equipment, onshore and offshore crane, excavator, concrete machine, paper machine, plastic and rubber machine, weave machine, steel plant, electronic power plant, wind power generator, other construction and industry machines or equipments and other large rotary device.
