SFU 2005-4 Ball Screw Nut


The SFU 2005-4 Ball Screw Nut is a high-precision linear motion component designed for CNC machines, automation systems, and industrial equipment requiring smooth, accurate, and repeatable movement. Designed to operate on a 20 mm diameter screw with a 5 mm lead, it delivers efficient linear displacement with very low friction, making it suitable for both moderate-speed and moderate-load applications. Constructed from hardened alloy steel, the nut offers excellent durability, wear resistance, and long service life under continuous operation. Its 4-circuit internal recirculation design provides improved rigidity and reduced backlash, ensuring stable positioning accuracy even in demanding environments. Compatible with standard ball-screw supports and mounting blocks, the SFU 2005-4 Ball Screw Nut is a reliable choice for builders, machinists, and automation engineers who need precision and stability in their linear-motion systems.
