THK Co., Ltd. SHS25LV1 280LBSC1 Linear Guide Assembly

The THK SHS25LV1 280LBSC1 Linear Guide Assembly is a compact, high-rigidity LM guide built for precise, low-friction travel on a 280 mm rail, featuring a narrow LV-style block and a single bearing assembly. It is designed for demanding CNC machining centers, robotic automation systems, semiconductor equipment, packaging machinery, automated assembly lines, and precision inspection devices where repeatable positioning matters, and maintenance teams and system integrators use it for machine repairs, automation retrofits, and equipment upgrades. Key specifications include THK SHS-LV series caged-ball LM guide, rail length 280 mm, guide size 25 mm, rail width 23 mm, overall block height 36 mm, overall block width 48 mm, and overall block length 109 mm (block width B 35 mm, mounting hole spacing C 50 mm, mounting hole thread M6 × 6.5). Dynamic load rating is 36.8 kN and static load rating is 64.7 kN. Material is hardened bearing steel with a caged-ball ball retainer, seal configuration SS (standard), and lubrication available by grease or oil with a grease nipple B-M6F; rail mounting is bolt mounted from above. Notable features include a four-way equal-load design, self-aligning capability, compact narrow profile, high rigidity, low friction, and long service life.
