Performance Video

The OAV Granite Guide and Vacuum Preloaded Linear Dovetail Stage delivers ultra-precise linear motion where stiffness, smoothness, and stability are essential. Its granite guideways provide unmatched flatness, thermal stability, and structural rigidity, while the vacuum preloaded system ensures zero-contact, frictionless operation with consistent stiffness and repeatable motion.


The 775 x 1200 mm carriage offers a large, stable platform suitable for metrology, optical alignment, and precision assembly applications. Together, the granite guides and vacuum preload create a high-performance stage optimized for demanding environments in optics, semiconductors, and precision measurement systems.


Key Features:


Granite guideways for exceptional flatness, stiffness, and thermal stability


Vacuum preloaded for zero-contact, frictionless motion


Large 775 x 1200 mm carriage for stable, precise operation


High stiffness and load capacity for demanding applications
