Product Description

                                                      
Slewing Bearing
Slewing bearing introduction
Slewing bearing is also called slewing ring,  turntable bearing, and rotary table bearing.
Slewing bearing is a bearing that able to bear axial load, radial load and overturning torque.
Under normal circumstances, slewing bearing has their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions.
On the other hand, slewing  bearing  has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.

The professional forging equipment and advanced set-forging process are used.
Steel bar is heated with the medium frequency induction and its different positions temperature is measured with the thermometer. After heating and thermal hydraulic shear, they are forged in accordance with the needs of grind and expansion. Then they are groud and expanded with CNC grinding machine so that the products could meet the technological requirements in size and geometry
                                   

Although it is a rough grinding process,  we still strictly control the size accuracy and geometric accuracy to lay a solid foundation for the precise grinding quality
Stable tempering
We have stable tempering on the ring after the rough grinding to eliminate stress and further stabilize the size and geometric precision
Thus guarantee high-quality products

 

All products are produced with the spheroidal annealing to ensure the product temperature uniformity good internal structure and other characteristics which is beneficial to the next step turning and quenching.
Heat treatment with quenching and tempering
The heat treatment in strict accordance with advanced process and the precious control quenching ensure that the bright quenching effect be reached.
