Product Description

The slewing bearing is also called the slewing ring bearing or turntable bearing, rotary bearing. 

1- Product introduction
The slewing bearing is a large bearing that can bear comprehensive loads, and can bear larger axial and radial loads and overturning moments at the same time. Slewing ring bearings are generally equipped with mounting holes, internal gears or external gears, lubricating oil holes and sealing devices, which can make the host design compact, easy to guide, and easy to maintain. Slewing ring bearings have four-point contact ball bearings without gear, external gear and internal gear, double-row angular contact ball bearings, crossed cylindrical roller bearings, crossed tapered roller bearings and three-row cylindrical roller composite bearings series.

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. Application
Slewing bearings are widely used in real industry. They are called "joints of machines". They are mainly used in: truck cranes, railway cranes, port cranes, ship cranes, metallurgical cranes, ladle slewing tables, grabs Steel machines, clay guns, oxygen blowing equipment, container cranes, excavators, filling machines, and CT machine standing wave treatment equipment, navigation equipment, radar antenna mounts, missile launchers, tanks, robots, rotating restaurants, etc. At the same time, it can also design, develop and produce various special structure slewing bearings according to the specific requirements of users.

4.Material
The material grade is GCr15 or GCr15SiMn , 42CrMo, 5CrMnMo, etc.
