THK Co., Ltd. SR25V2UU280L Linear Guide Rail Assembly

The THK SR25V2UU280L Linear Guide Rail Assembly is a complete radial linear motion guide system featuring a 280 mm long SR25 rail paired with two SR25V guide blocks for smooth, precise, and high-rigidity motion in industrial automation. Designed for through-hole mounting, it uses a four-row recirculating ball raceway, with a 25 mm rail width, hardened alloy steel rail, and hardened bearing steel blocks to deliver high radial load capacity, self-aligning capability, compact design with large load capacity, and low noise along with high positioning accuracy. This assembly is commonly used in CNC machine tools, semiconductor manufacturing equipment, robotics, packaging machinery, and automated production lines, and maintenance teams and system integrators rely on it for OEM replacement, machine repair, retrofit projects, and new precision linear motion installations. Lubrication options include grease or oil.
