Product Introduction1. Defination
1) Slewing Bearing is a kind of comprehensive load which can be withstand the larger axial and radial load and tilting moment.
2) Standard : JB/2300-1999 and JB/2300-2011
3) Application: Widely used in Marine equipment, engineering machinery, light industry, machinery, metallurgical machinery, medical machinery, industrial machinery and other industries
2. Basic Structure
Slewing bearing is consisted of worm, slewing bearing, shell, motor and other components.Because core part USES the rotary bearing, can also carry axial force and radial force and Titing moment.

Structure
Characteristic of structure, performance and application
The single row four point contact ball slewing bearing is composed of two seat rings, which design in
compact structure and light weight, steel ball contact with the circular raceway at four point, it can bear the
axial force, radial force and the tilting moment at the same time.
It can be used for slewing conveyer, welding manipulator, light & medium duty crane, excavator, and
other construction machinery.
Note:
1. n1 is the nos of lubricating holes.Oil cup M10×1JB/T7940.1~JB/T7940.2.The Oil nipple's location can
be change according to the user's application.
2. n-φcan change to tapped hole,the diameter of tapped hole is M,depth is 2M.
3. The tangential tooth force in the form is the max tooth force,the nominal tangential tooth force is 1/2 of the
max one.
4. "K" is addendum reduction coefficient.
