Ball Screw Nut Sfu1204 1-pack built for smooth installs and solid results
✔️ Ball Screw Nut SFU1204 (12mm Dia, 4mm Pitch) Ball Screw Single Nut for 1204 Housing CNC Machine Parts

This 1 pack is meant for clean replacement or upgrade work where fit and smooth operation matter.

✅ Parameter: SFU1204-3 ball screw nut shaft diameter：12mm(0.47"), Lead: 4mm(0.16"), Aperture: 4.5mm(0.18"), Single nut size: 40 x 30 x 35mm/1.57 x 1.18 x 1.38 inch (L*W*H).
✅ Material: The ball slider is made of bearing steel, which has strong rigidity, wear resistance, and high load-bearing capacity.
✅ Function: The ball screw kit can convert rotational motion into linear motion, or convert linear motion into rotational motion. It has the advantages of small dynamic moment, high dynamic and static stiffness, high and accurate positioning, low friction, low operating noise, and long service life.
✅ Application: Suitable for machining centers, CNC, semiconductor manufacturing equipment, machine tools, mechanical equipment, and transmission equipment.
✅ Package Includes: 1 set ball screw linear rail nut.

💡 How do you size a ballscrew kit to avoid backlash in CNC builds?
Quick answer: match pitch, travel length, and support style to your axis load and speed.
* Pitch controls feed rate and torque demand
* Proper end supports keep alignment tight under load
* Good lubrication cuts heat and wear over time

Built to keep motion smooth and accuracy steady during long production runs.
