This longer SFU1605 ball screw assembly helps deliver stable linear motion, reduced drive load, and consistent accuracy for CNC and automation applications that run longer axes.

💡 Why do CNC machines use high-efficiency ball screws instead of lead screws?
Ball screws are designed to convert rotary motion into linear motion with far less energy loss.

• Rolling ball contact greatly reduces friction and drive power demand

• Tight precision grades support smoother motion and cleaner positioning

• Low starting torque improves response in high-speed and micro-feed moves

• Better efficiency helps motors run cooler and last longer

A smart pick when you want smooth long-travel motion, better efficiency, and reliable accuracy in CNC and precision automation builds.
