THK Co., Ltd. SHS25C1SS LM Linear Bearing Block

The THK SHS25C1SS LM Linear Bearing Block is a flange-type C block designed for 25 mm THK SHS guide rails, delivering high rigidity and low-friction, four-way equal-load motion for demanding linear applications. Its compact housing measures 36 mm tall, 70 mm wide, and 92 mm long, with M8 mounting holes and top- or bottom-mounting options, using caged-ball technology and end/side/inner seals (SS) plus a grease nipple (B-M6F). The unit accepts 25 mm SHS rails with 23 mm rail width compatibility, and is manufactured in hardened bearing steel with a basic dynamic load rating of 31.7 kN and a basic static load rating of 52.4 kN. Widely used in CNC machining centers, robotic systems, semiconductor equipment, packaging machinery, automated assembly lines, and precision inspection machinery, maintenance teams and system integrators rely on it for machine repair, retrofits, and restoration of smooth, accurate linear motion. Common replacements include THK SHS25LC1SS, SHS25C1SS(GK), and HSR25A1SS.
