High-Precision CNC Ball Screws
Engineered for zero-backlash linear motion and maximum efficiency in CNC automation equipment.
A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings, acting as a precision screw for CNC Z-axis movement.
- High Precision: Ground ball screws offer C5 to C3 accuracy grades for extreme micromachining tolerances.
- Preloaded Nuts: Double-nut configurations eliminate axial backlash for perfect direction reversals.
- High Efficiency: Rolling ball contact achieves over 90% mechanical efficiency compared to acme lead screws.

Frequently Asked Questions
How does a ball screw differ from a lead screw?
A ball screw uses recirculating ball bearings to eliminate friction between the nut and the screw, resulting in over 90% mechanical efficiency, whereas a lead screw uses sliding friction which wears out faster and requires more motor torque.
What does a C5 accuracy grade mean?
The C5 grade indicates a highly precise ground ball screw with a lead error of less than 0.018mm per 300mm of travel, making it ideal for precision CNC milling.
How do you maintain a CNC ball screw?
Ball screws require regular lubrication with high-grade lithium grease or slideway oil, and must be protected from dust and chips using rubber wipers and accordion bellows.
