OAV Air Bearings
AS 9100 Rev D Certified
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 the one of the most widely used form of roller air bearing in the industry. 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 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.

Frictionless Outer Spin Air Bearings

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 in a fixed location. 

Frictionless Thrust Air and Gas Bearing and Bushings

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 aerospace quality titanium.

Frictionless Flat Rectangular Air and Gas Bearings

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.

Modular Dividable Air Bearings OAV

The modular air bearing design divides motion systems into smaller installable parts. OAV Modular Air Bearings can be independently installed and used in different systems and different shapes.

Air Bearing Linear Guides and Slides

OAV Profile Rail Guides are the next generation of OAV Air Bearings. Consisting of the Box Series, T-Series, and the U-Series, they are light weight and made with aircraft quality material.  They are 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. Non-contact rollers replace the standard contact conveyor systems.
