THK Co., Ltd. HSR30-280L Linear Guide Rail System

Description:

The THK HSR30-280L Linear Guide Rail is a precision 30 mm profile linear motion rail designed for use with THK HSR30 series linear guide blocks. Manufactured from hardened carbon steel, this 280 mm guide rail features a 28 mm rail width, 26 mm rail height, and 80 mm mounting hole pitch, providing high rigidity, smooth linear travel, and excellent positioning accuracy. Commonly installed in CNC machine tools, industrial automation equipment, robotics, semiconductor machinery, and precision manufacturing systems, this guide rail is used by maintenance teams, OEM machine builders, and system integrators for equipment repair, retrofit, expansion, and replacement.

Applications:

The THK HSR30-280L Linear Guide Rail is widely used in CNC machining centers, automated assembly systems, robotic positioning equipment, semiconductor manufacturing machines, packaging machinery, inspection systems, and precision material handling equipment. Its compact 280 mm length makes it ideal for short-stroke linear motion applications requiring high load capacity, low friction, and precise repeatability.
