Industrial Ball Screw End Blocks 550mm Ball Screw

A 550 mm ball screw assembly with end blocks delivers precise linear motion by converting rotary movement in CNC and automation systems. The assembly measures 550 mm in length, with a 15 mm screw diameter and 13 mm lead (pitch), and a 10 mm end-shaft diameter that accepts standard support hardware. A recirculating ball nut rides on a hardened steel screw, with alloy steel nuts providing durability and smooth, low-backlash travel; lubrication is grease- or oil-compatible. The included fixed end support blocks mount to a machine bed, offering stable alignment for repeatable positioning and long service life. With high mechanical efficiency from rolling ball elements, this ball screw is suited to medium- to high-axial-load applications in CNC mills, CNC routers, precision positioning stages, robotic actuators, and automated production equipment that demand stable, high-accuracy linear motion. Accuracy grades are manufacturer-dependent (precision ground or rolled), reflecting variation in production processes.
