Precision 20mm Ball Screw Kit For Tight CNC Router Builds
✔️ SFU2005 model includes nut housing and coupling support extras

This assembly turns rotational force into controlled linear travel for automation tasks. Builders often mount this unit along x or y axes for improved repeatability.

✅ 20mm screw diameter supports high accuracy linear moves
✅ Includes BK15 BF15 ballnut housings for motor setup
✅ RM2005 coupling connects screw to drive system gear
✅ 250mm effective length designed for compact build area

💡 Why select precise leads versus rack gears for motion?
Reduced backlash improves surface finish during finishing operations.
- Friction coefficients stay low minimizing energy waste during cuts
- Rigidity gains allow heavier depth of cut without deflection
- Servo loads decrease because mechanical advantage increases
