Hollow Strong Cooling Ball Screw

With the high-speed transmission mechanism, especially in the high-precision positioning of the ball screw will occur thermal expansion, our company adopts the hollow ball screw forced cooling method to solve the problem. The ball screw shaft end (sealing part and supporting bearing part) is standardized and recommended to users as the most effective and low way to reduce thermal expansion. In addition, there is a nut cooling ball screw, the product is designed with a cooling structure inside the nut, is a simple way to effectively cool, used for high-speed, high-precision ball screw. Due to the use of nut cooling, cooling is possible for some ball screws that are difficult to cool in a hollow way, and the corresponding range covers the high-precision needs of machine tools from small to large.

Installation precautions:

1. When installing on the ball screw shaft, grease the sealing lip, taking care not to damage the sealing lip.

2. After the sealing unit is installed, ensure that the drainage holes face down.

The bearing used in the support unit is a high-precision and high-stiffness thrust angular contact bearing dedicated to the ball screw, and the combination has the following three kinds.

8. Locknut

7. Hex socket cylindrical head screws

6. Supporting unit gland

5. Supporting unit gasket

4. Special bearing used for ball screw

3. Support unit shell

2. Oil seal

1. Support unit shaft ring
