THK SHS20C2QZZZS640LE Linear Guide Rail Assembly

The THK SHS20C2QZZZS640LE Linear Guide Rail Assembly delivers precise, low-friction linear motion in a 640 mm rail with a 20 mm guide size, configured as a four-way equal-load LM guide with a caged ball retainer. It uses an integrated QZ lubricator, bolt-fixed mounting, double-end seals, a two-bearing-block arrangement (SHS20C), and is designed for high rigidity, smooth travel, and long-term maintenance-free operation. Operating temperature ranges from -15°C to 80°C, with grease or oil lubrication. Common applications include CNC machining centers, robotic systems, semiconductor manufacturing equipment, packaging machinery, automated assembly lines, and precision inspection machines, with maintenance teams and system integrators using it for machine repair, automation retrofits, linear motion upgrades, and worn rail replacements. Common replacements include THK SHS20C2SSC1+640L, SHS20LC2QZZZS640LE, and HSR20C2SSC1+640L.
