THK Co., Ltd. HRW35-760L(GK) Linear Guide Rail

The THK HRW35-760L(GK) Linear Guide Rail is a precision wide-profile linear guide rail designed to provide smooth, accurate, and high-rigidity linear motion when paired with compatible THK HRW35 carriage blocks. With a 760 mm rail length and 35 mm nominal rail size, the rail measures 62 mm wide by 18 mm high and uses through-hole mounting with an 80 mm mounting hole pitch; End Distance (G) is 20 mm. Manufactured from hardened bearing steel and finished to 58–64 HRC, it employs a recirculating ball guide mechanism in the GK Series wide-profile, low-center-of-gravity design to deliver four-way equal load capability, high rigidity, and precise positioning with self-alignment and low-friction operation. It is commonly installed in CNC machining centers, robotic transfer systems, semiconductor processing equipment, automated assembly lines, packaging equipment, and other heavy-duty factory automation systems. Maintenance teams, machine builders, and system integrators rely on this guide rail for equipment repairs, machine retrofits, and replacement of worn linear motion components in demanding industrial applications. Compatible bearing blocks include HRW35CA, HRW35CAM, HRW35CR, and HRW35CRM; lubrication is grease or oil compatible, and mounting is through-hole. This part is part of the THK Brand as the HRW Wide-Rail LM Guide GK Series, with longer-length replacements such as HRW35-1000L(GK), HRW35-1240L(GK), and HRW35-1560L(GK) available for extended configurations.
