✔️ 12mm bore 4mm pitch premium bearing steel leadscrew

This single ball screw assembly pairs a hard chromed threaded rod with a matching nut to handle precise positioning tasks. You mount it straight into router cages, 3d printers, or light duty cnc machines where consistent linear motion matters.

✅ 1500 mm overall length provides ample travel range for bigger frames
✅ C7 precision class maintains tight tolerances during rapid moves
✅ Smooth machined surface prevents friction while reducing maintenance time

💡 How do you properly preload a cnc ball screw to stop backslash during heavy cuts?

A solid preload setup keeps your stepper motor locked against the nut so every direction change stays exact. This handy trick locks down your axis travel for years.

- Align the thrust bearing washers evenly before tightening the lock nuts - Monitor the torque wrench reading until the slider glides smoothly - Check lateral play once assembled to guarantee zero dead zones✝️
