Rolling Ball Screw Standard Nut Type Shaft Diameter 32 Lead 5/10/32

Frequently Asked Questions about This Product

1. Can ball screws and nuts be purchased separately?
Considering the precision and preload level of the assembled finished product, the precision of single ball screws and nut semi-finished products can only be guaranteed to be at the ordinary level, and the preload cannot be adjusted, which may lead to situations where they cannot be properly fitted.
If you need to purchase them, you can make remarks based on the standard model or consult relevant staff.

2. What is the upper temperature limit for the use of standard model ball screws?
The upper temperature limit for the use of ball screws is 8 °C. Exceeding this limit will cause damage to the circulating components and seals as well as deformation of the screw shaft and nut, affecting the service life.
Grease has a good effect on reducing temperature. Therefore, regularly injecting grease and performing other maintenance on ball screws will increase the service life of the screws.

3. What is the difference between C7-level precision and C5-level precision of ball screws?
The forming processes are different. C7 is cold-rolled, while C5 precision is ground. The precision of C5 level is higher than that of C7 level. C5 precision is suitable for application scenarios with higher precision requirements, while C7 precision is suitable for application scenarios with lower precision requirements.

4. Why do ball screws rust and how to deal with and prevent it?
The material of ball screws does not have anti-rust ability. They will rust when the air humidity is high, there is no oil film covering the surface or they come into contact with corrosive liquids.
If there is slight rust on the non-rolling groove parts and it does not affect the use, you can polish it with sandpaper of 1200 mesh or above and then reapply anti-rust oil.
You can perform hard chrome plating or black chrome plating on the screw thread surface to improve the corrosion resistance performance, or use physical isolation (such as adding bellows covers for protection).

5. Why do ball screws get stuck?
1）Excessive load;
2）Improper lubrication;
3）The nut is too tight;
4）Balls are dropped due to over-travel use.
