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 number of lubricating holes.Oil cup M10x 1JB/T7940.1~JB/T7940.2.The Oil nipple's location can be changed according to the user's application.
2. n-Φ can be changed to tapped hole,the diameter of tapped hole is M,depth is 2M.
3. The tangential tooth force in the form is the maximum tooth force,the nominal tangential tooth force is 1/2 of the max one.
4. "K" is addendum reduction coefficient.
