✔️ 1940mm precision screw, anti-backlash nut, steel mounts, and coupler

This ready-to-roll assembly transforms your stepper motor into a reliable linear motion system. You get a complete drive set built for CNC routers and garage fab projects. Just mount the unit to your frame and hook the controller to start precise positioning work today.

✅ 25mm shaft diameter (~0.98 inch) with 4mm lead (~0.16 inch) for smooth travel
✅ 1940mm total length (76.38 inches) covers larger build areas
✅ C7 precision grade minimizes play and improves repeatability
✅ Cast steel end supports handle heavy loads without flex
✅ 14mm flexible coupler (0.55 inch) matches standard NEMA 34 motor shafts

💡 How do precision ball screws improve accuracy in DIY CNC builds?
A direct drive linear motion setup cuts down on maintenance and keeps your project moving smoothly.
- Reduced friction means your stepper motor draws less current during operation
- Higher load capacity handles heavier cuts without bending or wearing out fast
- Consistent feedback loops give you tighter tolerance control on every pass
- Easy swap-in design makes upgrading an existing router table completely handy
