THK Co., Ltd. SHS25LC1QZZZ Unmounted Bearing Blocks

Description:

The THK SHS25LC1QZZZ Unmounted Bearing Block is used in precision linear motion systems requiring high load capacity, extended service life, and smooth linear travel on THK SHS25 guide rails. Commonly installed in CNC machining centers, robotic automation systems, semiconductor manufacturing equipment, packaging machinery, automated assembly lines, and precision inspection equipment where a long-type SHS25 bearing block with QZ lubrication and metal scraper protection is required. Maintenance teams and system integrators use this bearing block for machine repair, linear guide replacement, automation retrofits, and restoration of accurate, low-friction linear motion.

Applications:

The THK SHS25LC1QZZZ is designed for heavy-duty linear motion applications requiring high rigidity, four-way equal load capability, and long-term maintenance-free operation. It is widely used in CNC machine tools, electronics manufacturing equipment, factory automation systems, medical devices, material handling equipment, pick-and-place machines, and automated inspection systems where precise positioning, low noise, and long operating life are essential.
