The DOV-150-150-XY-M100 is a compact, ultra-precision XY planar air bearing platform formed by stacking two OAV Profile Dovetail-Series Air Bearing Rail Guides in an orthogonal configuration. This architecture delivers coordinated planar motion with exceptional straightness, stiffness, and smoothness, making it ideal for applications where space efficiency and deterministic positioning are critical.

Each axis incorporates OAV’s porous graphite air bearing technology, providing uniform air distribution and true non-contact motion. Vacuum preloading actively constrains the bearings, resulting in high structural stiffness, excellent damping, and outstanding repeatability—without friction, backlash, or mechanical wear. The dovetail rail profile ensures inherent guidance stability and precise orthogonality between stacked axes.

Manufactured from premium aircraft-grade materials and finished to extreme flatness and linear accuracy, the DOV-150-150-XY-M100 is factory-matched and aligned to preserve precision across the full travel range. The platform is delivered ready to install, requiring no field adjustment and maintaining performance over time with zero maintenance.

An integrated air-actuated locking brake function, achieved through controlled air bearing pre-tensioning, allows the stage to securely hold position when required—without introducing mechanical contact or compromising accuracy.

Clean, vibration-free, and maintenance-free, the DOV-150-150-XY-M100 is ideally suited for precision optics, semiconductor processes, advanced metrology, and research systems requiring ultra-smooth planar motion.
