SMH280LM Series
Cost-Effective Mechanical Direct-Drive Linear Stage
The SMH280LM series is powered by a linear motor, delivering high speed, superior dynamics, and low friction—ideal for precise position control in long‑stroke, high‑velocity, and high‑accuracy applications.
Equipped with high‑resolution optical scales (electronic resolution down to 1 nm), the SMH280LM achieves sub‑micron repeatability and positioning accuracy through calibration. Its low‑friction side seals protect against dust and particles, ensuring long‑term reliability and extended maintenance intervals. Cable management options are available, and the side seal design simplifies routine upkeep.
As a critical component in precision machinery, the SMH280LM is widely used in OLED cutting, PCB drilling, CNC machining, biotechnology, IC packaging, and surface metrology—offering a robust solution that combines precision positioning, high speed, and heavy load capacity.
