This long-travel SFU1605 setup delivers clean linear motion, reduced friction, and dependable positioning for extended CNC axes and automation systems.

💡 Why are long-travel C7 precision ball screws used in high-accuracy CNC motion?
Long ball screws are designed to keep motion smooth and positioning consistent across large travel distances.

• Rolling ball contact lowers friction and drive power needs

• Matched nut assemblies help control backlash and alignment

• Low starting torque supports smoother acceleration and deceleration

• Wear-resistant surfaces extend service life under continuous motion

A strong option when you want smooth long-range travel, steady accuracy, and reliable performance in CNC and precision automation applications.
