THK SR25V High Precision Linear Guide Rail Assembly

The THK SR25V High Precision Linear Guide Rail Assembly combines a 220 mm SR25 rail with two SR25V carriages to deliver precise, high-rigidity linear motion in automation systems. A four-row recirculating ball raceway, with carriage dimensions approximately 55 mm × 48 mm and hardened bearing steel rail and carriage, supports a basic dynamic load rating of 30.9 kN and a basic static rating of 44.7 kN, with lubrication options of grease or oil and mounting via through-hole rail mounts. Commonly installed in CNC machine tools, semiconductor equipment, robotics, packaging machinery, inspection systems, and automation equipment, this assembly is used for OEM replacement, machine repair, retrofit projects, and new precision motion systems, and is favored by maintenance teams and system integrators for reliable, repeatable positioning.
