Small Diameter Slewing Ring Bearing Rothe Erde with External Gear
Characteriestic 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 tlting moment at the same time.
It can be used for slewing conveyer, welding manipulator, light & medium duty crane, excavator, and other construction machinery.
Gear heat treatment
The statement of gear heat treatment normally have two statement, normfalizing and tempering. The quenching of gear surface an processed according to customer's requirement, the hardness are in the range of 50HRC~60HRC. In different application, the gear quenching can divide into whole tooth quenching and single tooth induction quenching, the latter one can divide into tooth surface & root quenching and tooth surface quenching.
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.
Small diameters and thin sections slewing bearing (061 series) are the main characteristics of crane application. These particular slewing bearings require strict process control. The xuzhou wanda Slewing Bearings are very well-known in the world to accept the highest rotating speed and to control the temperature during working 24 hours a day. Our quality gives a very low level of maintenance. The Xuzhou Wanda slewing bearings manufacture millions of bottles all around the world everyday.
