What Is a Linear Motion Ball Screw?
A linear motion ball screw is a mechanical transmission component that uses rolling balls between the screw shaft and nut raceway. When the screw rotates, the nut moves linearly along the shaft, providing efficient and accurate motion transmission.
Because the contact form is rolling friction rather than sliding friction, a ball screw can reduce driving torque, improve movement smoothness and support more reliable positioning in CNC machines, industrial robots, measuring equipment, medical devices and automated production lines.

Ball Screw vs. Ordinary Sliding Screw
For equipment that requires precision, speed and repeated positioning, ball screws are usually preferred over ordinary sliding screws.
| Item | Ball Screw | Ordinary Sliding Screw |
|---|---|---|
| Friction Type | Rolling friction | Sliding friction |
| Friction Coefficient | About 0.001–0.005 | About 0.05–0.15 |
| Transmission Efficiency | About 90%–96% | About 20%–40% |
| Accuracy Level | Suitable for micron-level positioning | Usually suitable for lower precision movement |
| Typical Use | CNC, automation, robots, precision equipment | Simple adjustment, low-speed transmission, low-cost mechanisms |

Send Your Requirement Email Your DrawingHow to Select the Right Ball Screw
1. Confirm Diameter and LeadSmaller lead is better for fine feeding. Larger lead is suitable for faster linear movement. |
2. Confirm Accuracy GradeC5 is used for higher precision equipment. C7 is widely used in general automation. |
3. Confirm Stroke LengthLong-stroke screws need attention to rigidity, support method, speed limit and installation alignment. |
4. Confirm End MachiningBearing seat dimensions, motor coupling size, thread, keyway and flat position should be confirmed. |
Send us your required stroke, load, speed, accuracy grade, installation drawing or machine type. DLY engineers can help recommend a suitable ball screw model.
