Heavy Duty 400mm Rolled Ball Screw Matched With Anti Backlash Ball Nut Engineered For CNC Machines Delivering Rock Solid Reliability And Ridiculously Smooth Linear Motion Control

Precision 400mm CNC Ball Screw Assembly for Smooth Motion
✔️ 400mm length, 12mm shaft, 4mm pitch, silver finish, 367g

You get a single 400mm / 15.75inch unit with a 12mm / 0.47inch shaft and 4mm / 0.16inch pitch. This rolled ball screw kit delivers steady linear motion for your CNC router or milling project. The anti backlash nut keeps cutting precise while reducing vibration during heavy material removal.

✅ High transmission efficiency lets balls roll smoothly inside the nut
✅ Eliminates stick slip friction so your machine saves drive power
✅ Low frictional loss cuts down heat buildup during long machining runs
✅ Improved torsion control gives accurate positioning without creeping slides
✅ Package includes one 400mm / 15.75inch silver rolled ballscrew unit

💡 How does an anti backlash ball nut maintain tight tolerance during heavy milling passes?

The preloaded nut design keeps your rig tracking straight when pushing through steel. Here is how it stays handy on the job site.
- hardened chrome shaft handles continuous load without deformation
- sealed recirculating balls reduce wear around the threaded grooves
- matched nut assembly limits play to guarantee repeatable cutting paths
- efficient friction transfer cuts motor strain during rapid traversals
