THK Co., Ltd. HRW27-340L Linear Guide Ball Rail

Description:

The THK HRW27-340L Linear Guide Standard Ball Profile Rail is a precision wide-profile linear guide rail designed for use with compatible THK HRW27 carriage blocks, providing smooth, rigid, and highly accurate linear motion. Commonly installed in CNC machine tools, semiconductor manufacturing equipment, industrial robots, packaging machinery, and automated production systems where high rigidity and precise positioning are required. Maintenance teams, OEM machine builders, and system integrators use this guide rail for equipment repairs, rail replacements, automation retrofits, and precision linear motion system upgrades.

Applications:

The THK HRW27-340L guide rail is widely used in CNC machining centers, robotic transfer systems, semiconductor processing equipment, pick-and-place machines, packaging equipment, vision inspection systems, and factory automation applications requiring a compact, wide-profile linear guide capable of supporting high moment loads and delivering accurate, low-friction linear travel over a 340 mm rail length.
