THK HSR25A1SS(GK) Linear Motion Guide Slide Block

Description:

The THK HSR25A1SS(GK) Linear Motion Guide Slide Block is a precision recirculating ball linear bearing carriage designed for use with THK HSR25 series guide rails. As part of THK's Global Standard (GK) interchangeable series, it features an A-type flange block with SS sealing (end seals, side seals, and inner seals) for enhanced protection against contaminants while providing smooth, high-rigidity, and low-friction linear motion. Commonly installed in CNC machine tools, industrial robots, semiconductor equipment, packaging machinery, and factory automation systems, this bearing block is used by maintenance teams, OEM machine builders, and system integrators for equipment repair, retrofit, expansion, and replacement. It is manufactured in Japan.

Applications:

The THK HSR25A1SS(GK) Linear Motion Guide Slide Block is widely used in CNC machining centers, robotic positioning systems, semiconductor manufacturing equipment, automated inspection machines, medical equipment, packaging machinery, and precision industrial automation systems requiring high rigidity, smooth linear travel, accurate positioning, and long service life. The interchangeable GK design allows convenient replacement while maintaining machine accuracy.
