Frictionless Air and Gas Bushings

Technological advancements have allowed air bearings to offer inherent advantages over traditional bearings, as well as the opportunity to be used for a much broader range of applications. OAV Air Bushings are ideal for linear and rotary based applications.

Frictionless Tapered Roller Air Bearings

The tapered air bearing is one of the most widely used forms of roller air bearings. The OAV Tapered Roller Air Bearing consists of two main components - the inner assembly, and the outer-cage. It is typically mounted in opposing pairs on a shaft, with air supply coming through the shaft with a cross-hole or inlet from the outer-cage.

Frictionless Outer Spin Air Bearings
Frictionless Thrust Air and Gas Bearing and Bushings

With the ability to spin outer rings at an incredible accuracy of .025 microns, the Outer Spin Rotary Air Bearing is a breakthrough product that replaces conventional bearings. It is ultra-precise and hard-installable.

For the first time, an air bearing is available that fully integrates and works on a three-way frictionless surface. OAV Thrust Air Bearings and Bushings run on  standard size shafting fix and maximizes stiff motion with precision. Made with aircraft quality material.

Frictionless Roller Air and Gas Bearings

The OAV Roller Air Bearing preloads both horizontal and vertical surfaces with opposing thin films of pressure. This maintains the perfect gap for ultimate tolerance. The surface design equally distributes air and preloads it over an entire surface area for outstanding stiffness and maximized performance.


We offer a line of flat rectangular air bearings designed to meet the non-contact requirements at low cost while yielding high performance. 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 and custom sizing made to order upon request.

Air Bearing Linear Guides and Slides

OAV Profile Rail Guides are the next generation of OAV Air Bearings. Consists of the DOV series, Box Series, T-Series, and the U-Series. Manufactured with aircraft quality material. Made for easy retrofitting into existing applications or designing into new applications.

Vacuum Preloaded Air Bearings

The OAV Vacuum Preloaded Air Bearing uses a combination of air pressure and a vacuum for increased control over fly height and air gap stiffness.

Frictionless No Contact Static Web Rollers OAV

OAV Non-Contact Static Web Rollers are used for applications that include the use of flexible materials while reducing contaminants and damage. Web tension, edge guiding, and more. Non-contact rollers replace the standard contact conveyor systems.
