THK Co., Ltd. SHS30LC1SS (GK) Block Linear Guide

Description:

The THK SHS30LC1SS (GK) Block Linear Guide Standard Ball Bearing Block is used in precision linear motion systems requiring a long wide-type carriage for high load capacity, rigidity, and smooth linear travel on THK SHS30 guide rails. Commonly installed in CNC machining centers, robotic automation systems, semiconductor manufacturing equipment, packaging machinery, automated assembly lines, and precision inspection equipment. Maintenance teams and system integrators use this bearing block for machine repair, replacement of worn linear guide carriages, automation retrofits, and restoring accurate, low-friction linear motion.

Applications:

The THK SHS30LC1SS (GK) is designed for heavy-duty linear motion applications requiring high rigidity, long carriage support, and precise positioning accuracy. It is widely used in CNC machine tools, industrial automation systems, electronics manufacturing equipment, material handling machinery, medical devices, pick-and-place systems, and automated inspection equipment where reliable, repeatable linear guidance is essential.
