THK SR20W1SSGK Block Linear Guide Stainless Steel

The THK SR20W1SSGK Block Linear Guide is a wide-type stainless steel radial LM block designed for THK SR20 guide rails, delivering smooth, low-friction, high-rigidity linear motion for precision automation. It features a four-row recirculating-ball raceway and a stainless steel carriage to provide reliable performance with corrosion resistance, compatible with a 20 mm rail width; carriage length is 66.2 mm and carriage width 42 mm, while dynamic and static load ratings are 12.5 kN and 25.2 kN respectively. The block includes SS end/side/inner seals and supports grease or oil lubrication, making it suitable for CNC machine tools, semiconductor equipment, robotics, packaging machinery, optical inspection systems, and automated production lines; maintenance teams and system integrators rely on it for OEM replacements, retrofits, and new precision linear-motion assemblies where high positioning accuracy, moment-load resistance, and long service life are essential.
