THK Co., Ltd. SHS25R1SS(GK) Linear Bearing Guide Block

The THK SHS25R1SS(GK) Linear Bearing Guide Block is a 25 mm square‑type carriage designed for use with THK SHS25 rails, delivering smooth, low‑noise, high‑rigidity motion for precision linear systems. This recirculating‑ball guide block uses THK's ball retainer technology and GK seal configuration (end, side, and inner seals) for long service life, with an assembly height of 40 mm, block width 48 mm, and block length 92 mm; mounting hole spacing 35 × 35 mm and mounting thread M6 × 8, rail mounting pitch 60 mm, and rail width compatibility 23 mm. It supports a dynamic load rating of 31.7 kN and a static load rating of 52.4 kN, and is made from hardened bearing steel. Common applications include CNC machining centers, industrial robots, semiconductor manufacturing equipment, packaging machinery, medical and optical inspection systems, automated assembly and material handling, and other precision motion systems; it is frequently used by maintenance teams, OEM machine builders, and system integrators for repairs, retrofits, and replacement of worn linear guide carriages. Common replacements include THK SHS25C1SS(GK), THK HSR25A Linear Guide Block, and THK SSR25XW Linear Guide Block.
