775 mm x 1200 mm Dovetail Granite Rail Guide
Performance Note: Load, stiffness, flow rate, and moment values are based on testing at 60 PSI supply pressure. Actual performance may vary depending on shaft quality, mounting method, air supply stability, and application conditions.
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
