Thk SHS25V2QZSS280L-II Linear Guide Rail Assembly

Description:

The THK SHS25V2QZSS280L-II Linear Guide Rail is used in precision linear motion systems requiring two narrow standard-type bearing blocks with integrated QZ lubrication on a 280 mm guide rail for smooth, accurate, and maintenance-efficient 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, 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 systems.

Applications:

The THK SHS25V2QZSS280L-II is engineered for high-precision industrial applications requiring low friction, high rigidity, and long maintenance intervals. Its integrated QZ lubricator continuously supplies lubricant to the raceways, making it ideal for CNC machine tools, factory automation equipment, electronics manufacturing, semiconductor production systems, medical devices, material handling equipment, pick-and-place machines, and automated inspection systems.
