THK SR25V High Precision Linear Guide Rail Assembly

Description:

The THK SR25V Linear Rail with 2 Carriages is a precision radial-type linear motion guide assembly consisting of one 220 mm SR25 guide rail and two SR25V linear guide blocks, designed to provide smooth, accurate, and high-rigidity linear motion in industrial automation systems. Commonly installed in CNC machine tools, semiconductor equipment, robotics, packaging machinery, inspection systems, and factory automation equipment where precise positioning and high load capacity are required. Maintenance teams and system integrators use this linear guide assembly for OEM replacement, machine repair, retrofit projects, and new precision motion system installations.

Applications:

The THK SR25V Linear Rail assembly is designed for precision linear motion applications requiring excellent radial load capacity, smooth travel, and high rigidity. The 220 mm rail combined with two SR25V guide blocks provides improved load distribution and stability, making it suitable for automated assembly equipment, pick-and-place systems, electronic manufacturing machinery, laboratory automation, medical devices, optical inspection equipment, and material handling systems.
