Applications of ball screws
Machine tools：One of the main examples that uses ball screws for their high-tech characteristics is machine tools. Balls screws are used to provide linear motion that is required in many different types of machines including lathes, milling machines and other computer numerical control (CNC) machines.
Robotics：Ball screws are also used in various types of robotic applications due to their smooth and accurate characteristics. You can find them in many robotic arms and legs, giving these unique technological advancements the ability to move.
Aerospace systems：In many aircraft control systems, you can find ball screws due to their accuracy and low friction tendencies. Ball screws can also be found in many other aerospace applications.
The Mechanical Ingenuity of Ball Screws
A ball screw is a mechanical apparatus designed to convert rotational motion into linear motion. The fundamental elements of a ball screw comprise a nut and a screw featuring helical grooves, along with ball bearings. The balls move in a continuous path between the nut, the screw, and the grooves, orchestrated by the rotation of either the screw or the nut. They follow a trajectory within the ball return system of the nut, traversing from the initial point to the endpoint and then returning to the starting position. Wipers are strategically positioned on either side of the nut to act as a protective shield against debris, which can shorten the life of the ball screw assembly.
Maintenance and Lubrication
Regular Maintenance
Performing regular maintenance on ball screws is crucial for preserving accuracy and precision. Cleaning, lubrication, and inspection can help prevent wear and ensure consistent performance over time.
Lubrication Selection
The type and quality of lubrication used in ball screws play a significant role in maintaining precision. Proper lubrication reduces friction, minimizes wear, and contributes to smoother linear motion.

Questions That 99% Of Buyers Will Ask
1. What accuracy grades do you offer for ball screws?
A: We offer C3, C5, C7, and C10 accuracy grades according to JIS standards. C3 and C5 are suitable for high-precision CNC machines, while C7 and C10 are commonly used in automation and general machinery.
2. What is the lead accuracy and backlash of your ball screws?
A: The lead accuracy depends on the selected grade. For example, C5 grade lead error is ±0.023 mm per 300 mm. Preloaded ball screws can achieve near-zero backlash. Standard C7 grade typically has 0.02–0.05 mm backlash.
3. What materials are used for the screw shaft and nut?
A: The screw shaft is usually made of SCM415 / SCM420 alloy steel or 42CrMo, with surface hardness HRC58–62 after heat treatment. The nut is typically made of bearing steel such as GCr15.
4.What are the dynamic and static load ratings?
A: The dynamic (Ca) and static (Coa) load ratings vary by model and size. Detailed technical data sheets and load calculation support are available upon request.
5. Do you provide preloaded ball screws?
A: Yes, we offer different preload options such as light preload, medium preload, and heavy preload to meet various precision and rigidity requirements.
6. What surface treatments are available?
A: Standard surface treatment is anti-rust oil protection. Optional treatments include black oxide, hard chrome plating, and nickel plating depending on application requirements.
7. Can you provide customized ball screws?
A: Yes, we support customization including special end machining, non-standard lead, special nut design, and OEM production based on drawings or samples.
8. What is your production lead time?
A: Standard models are usually ready within 7–15 days. Customized products typically require 20–30 days depending on specifications and quantity.
9. What certifications do you have?
A: Our production process complies with ISO9001 quality management standards. RoHS compliance and material reports can be provided upon request.
10. What industries use your ball screws?
A: Our ball screws are widely used in CNC machine tools, automation equipment, robotics, medical devices, injection molding machines, and semiconductor equipment.
