Where aerospace technology meets air bearing systems

Non-Contact Ultra Precision Motion

Through recent technical advances, air bearings offer inherent advantages over traditional bearings as well as create opportunity for a much broader range of applications. OAV Air bearings offers integrated air bearings, aerospace materials and standardization of product and proven performance in the most demanding applications.

Our flat round air bearing works on flat, nonporous surfaces such as granite, aluminum, glass, and ceramics We offer a variety of sizes which can easily be used to customize air bearing systems. 

Oav Roller Air Bearings pre-loads both horizontal and vertical surfaces with opposing thin film pressure. This maintains the perfect gap for ultimate tolerance. OAV Air Bearings surface design equally distributes the air and pre-load over a entire surface area; the result; outstanding stiffness and maximized performance.

The Outer Spin Rotary Air Bearing is yet another significant advancement produced by OAV Air Bearings. This innovative product is hard-installable and ultra precise with a fixed location. Here to replace your conventional bearing.

Our Patent Pending OAV thrust air bearing is a breakthrough innovation in air bearing technology. For the first time, an air bearing is available that fully integrates and works on 3 way Frictionless surface. OAV Thrust air bearings runs on standard size shafting fix or linear motion while maximizing stiff motion and ultra precision with Aerospace quality Titanium.

We offer a line of flat rectangular air bearings designed to meet the non-contact requirements at low-cost while yielding high performance. OAV Flat Air Bearings are often used as a standard, off-the-shelf solution for providing axial constraint in rotary motion applications. Our standard product line is available in metric sizing as well as the custom sizing made to order upon request.

Modular Air Bearing design subdivides motion systems into smaller installable parts. OAV modular air bearings can be independently install and then used in different systems and different shapes.

OAV Profile Rail Guides consists of the next generation Oav Air Bearing. Manufactured from aircraft quality, light weight linear guides, Box Series, T-Series and U-series.  It is a complete offering of air bearing slides in a wide range of styles, sizes, and unique features produced for easy retrofitting into existing applications or designing into new applications

Oav Vacuum Pre-loaded Air Bearing are a combination of air pressure and vacuum. Air bearings hold it down while simultaneously lifting from the surface.
