THK SR20W1SSGK BLOCK LINEAR GUIDE SR SERIES

Description:

The THK SR20W1SSGK Block Linear Guide is a wide-type stainless steel radial linear guide block designed for THK SR20 guide rails, providing smooth, high-rigidity, and low-friction linear motion for precision industrial automation systems. Commonly installed in CNC machine tools, semiconductor manufacturing equipment, robotics, packaging machinery, optical inspection systems, and automated production equipment requiring accurate and stable linear guidance. Maintenance teams and system integrators use this guide block for OEM replacement, machine repair, retrofit projects, and new precision linear motion assemblies.

Applications:

The THK SR20W1SSGK is engineered for precision linear motion applications requiring high rigidity, excellent radial load capacity, and reliable resistance to moment loads. Its wide-body four-row recirculating ball design makes it ideal for automated assembly equipment, electronic manufacturing machinery, laboratory automation, medical devices, pick-and-place systems, precision inspection equipment, and material handling systems where smooth, repeatable positioning is essential.
