Need a precise replacement part for your CNC machine or DIY project? This is a high-quality ball screw nut, model SFU1605. The specs are right in the name: it fits a 16mm diameter ball screw and has a 5mm pitch. It's made from tough bearing steel, which means low friction, a long service life, and it runs pretty quietly. The nut itself has an outer diameter of about 28mm, a flange diameter of 48mm, and a height of 42mm. It's designed to convert smooth rotational motion into accurate linear motion, which is critical for CNC milling, 3D printers, or any precision machinery. The package includes the ball screw nut and a black rod. Easy to install if you're replacing an old one on a compatible SFU1605 ball screw. A solid, reliable component for makers, machinists, and hobbyists working on automation or precision tool projects.
