High Quality Four Point Contact Ball Slewing Bearing for Aerial Platform Vehicles

The loads and working conditions defined and gathered by the customer in our catalogue. Our XZWD Engineering Department to select the most suitable product.

The stiffness & preload of wanda slewing ring are a perfect solution for the highest Aerial platform vehicles. Those applications require precision in manoeuvring and safety while working in difficult environment subject to wind. Especially for firetrucks the highest stiffness ensure the highest efficiency in the works.

For Aerial platform vehicles usuall used single row four point contact ball slewing bearing with sizes center distance between 300mm to 700mm. The detail sizes list as below:

Single Row Four Point Contact Ball Slewing Bearing

(01 Series) External Gear

The single row four point contact ball slewing rings is composed of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four points; 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.

Our special design gives very compact bearings, which is essential for this product.Our process control gives the customer a very simple solution to set up the pinion in order to save time during the mounting of the machines.

The slewing ring, combining stiffness and integration of the bearing, slewing and fastening functions meets the
requirements of this application. Wanda is developing a new range of slewing rings in order to further improve the suitability.
