12mm Ball Screw Rod SFU1204 length 500mm with Single Ball Nut with end machining

The 12mm ball screw SFU1204 is a high-quality, precision-engineered component designed for various applications in CNC machines

• SFU1204 ballscrew engineered for smooth, accurate linear travel. This 12mm ball screw rod features a 4mm lead (pitch) that balances speed and precision, making it a practical choice for CNC positioning, printer bed/extruder movement, and automation slides.
• Manufactured from GCr15 bearing steel with C7 accuracy grade and a rolled thread process, the screw is built for stable performance and long service life.
• The included single ball nut helps reduce friction and improve efficiency compared to lead screws, while the end machining supports faster integration into supported bearing blocks, couplers, and motor mounts.
