Description
Technical Parameters

Manual linear translation stages deliver micron-level precise positioning with zero electromagnetic interference, ideal for optical calibration, fiber coupling and precision laboratory applications without power supply

Manual linear stages are precision mechanical positioning modules designed for accurate linear displacement of objects in planar and spatial dimensions. Assembled with base, sliding block, guide rail, handwheel and locking mechanism, they adopt dovetail grooves or cross roller rails paired with fine-tuning lead screws to achieve ultra-precise manual adjustment.

Different from electric linear slides, these manual positioning platforms require no power input and generate no electrical noise, which will never disrupt faint laser signals during optical path calibration. Built upon high-precision machining and assembly craftsmanship, the slide runs steadily and backlash-free along the rails. Equipped with micrometer barrels and micrometer screws for tiny incremental displacement tuning, our stages boast compact size, easy integration and long-term operational stability.

Developed by HCY Automation, our multi-angle high-precision manual displacement stages serve as essential foundational motion components for fine positioning scenarios across numerous precision industries.
