✅ 8 mm shaft diameter with SFK ball nut for smooth travel
✅ Heat-treated steel construction for wear resistance and long life
✅ Flange nut included for easy mounting on CNCs, routers, and stages
✅ Low noise due to efficient ball circulation design
✅ Length options: 100 mm, 150 mm, 200 mm
✅ Compatible with most CNC routers, linear stages, and motion control systems

💡 What is a ball screw used for in small DIY CNC and 3D printer projects?

A ball screw is a handy mechanism that converts rotary motion into precise linear travel with low friction.
- Converts rotary motion into linear travel for precise positioning
- Common in CNC machines, 3D printers, and linear actuators
- Offers low backlash and long service life with heat-treated steel
