This long-travel SFU1605 assembly helps maintain smooth linear motion, reliable positioning, and reduced drive load across extended CNC axes and automation systems.

💡 Why are long ball screws preferred for precise linear motion over extended travel?
Long ball screws are designed to keep accuracy and efficiency consistent even across large movement ranges.

  • Rolling ball contact minimizes friction over long distances

  • Matched nut and screw pairing helps control backlash and alignment

  • Low starting torque supports smoother acceleration and deceleration

  • Wear-resistant surfaces extend service life under continuous motion

A solid pick when you want clean long-range travel, steady accuracy, and dependable performance in CNC and precision automation builds.
