THK SHS35C2QZSS520L LINEAR GUIDE RAIL W 2 GUIDE BLOCKS #338227

Description:

The THK SHS35C2QZSS520L Linear Guide Rail Assembly is used in precision linear motion systems requiring two standard square-type bearing blocks with an integrated QZ lubrication system mounted on a 520 mm guide rail for smooth, accurate, and low-maintenance linear travel. Commonly installed in CNC machining centers, robotic automation systems, semiconductor manufacturing equipment, packaging machinery, automated assembly lines, and precision inspection equipment where high rigidity and long service life are required. Maintenance teams and system integrators use this linear guide assembly for machine repair, automation retrofits, equipment upgrades, and replacement of worn linear guide systems.

Applications:

The THK SHS35C2QZSS520L is engineered for demanding industrial applications requiring high load capacity, precise positioning, and extended lubrication intervals. The integrated QZ lubricator continuously supplies lubricant to the raceways, making this assembly ideal for CNC machine tools, factory automation equipment, semiconductor production systems, electronics manufacturing, medical devices, material handling systems, pick-and-place machines, and automated inspection equipment.
