This long-length SFU1605 assembly helps deliver clean linear motion, reduced vibration, and reliable positioning across extended CNC axes and automation setups.

💡 Why do long-travel CNC systems rely on high-stiffness ball screw assemblies?
Ball screws are engineered to maintain accuracy and efficiency even when travel length increases.

• High stiffness limits deflection and positioning drift

• Rolling ball contact reduces friction and operating noise

• Case-hardened surfaces improve wear resistance under load

• Stable motion helps maintain accuracy during long continuous runs

A solid choice when you want smooth long-range motion, quiet operation, and dependable performance in CNC and precision automation builds.
