Thk SHS25LV1 280LBSC1 Linear Guide Assembly

Description:

The THK SHS25LV1 280LBSC1 Linear Guide Assembly is used in precision linear motion systems requiring a narrow long-type linear bearing block mounted on a 280 mm guide rail for smooth, accurate, and high-load linear travel. Commonly installed in CNC machining centers, robotic automation systems, semiconductor manufacturing equipment, packaging machinery, automated assembly lines, and precision inspection equipment where compact-width, high-rigidity linear guidance is required. Maintenance teams and system integrators use this linear guide assembly for machine repair, automation retrofits, equipment upgrades, and replacement of worn linear motion components.

Applications:

The THK SHS25LV1 280LBSC1 is designed for demanding linear motion applications requiring high precision, low friction, and long service life in a compact installation space. It is widely used in CNC machine tools, electronics manufacturing equipment, medical devices, factory automation systems, material handling equipment, pick-and-place machines, and automated inspection systems where repeatable positioning accuracy and reliable linear motion are essential.
