Engineered for exacting tasks, this manual Z-axis linear stage uses a robust aluminum alloy dovetail sliding table with a 25x25mm platform and ±5mm travel range. Its screw-driven guide rail delivers smooth motion with 30μm straightness and 0.1mm scale resolution—each full rotation moves the stage ~0.5mm. Perfect for optical alignment, lab testing, and precision mechanical setup. Includes one ready-to-use unit.
