OAV Air Bearings is the leading manufacturer of the advanced air bearing technology. OAV are committed to providing our customers with the most precise bearing system available spread over many existing and emerging markets around the world.


OAV Air Bearings do not have mechanical contact between elements and benefit from an air-film averaging effect. Due to an absence of mechanical contact, the OAV Air Bearing has virtually no friction to generate heat and cause wear. We provide designs that are integrated into your product; we can develop a design based on an application or specific requirements.

flat round air bearings

Flat round air bearings work on flat, nonporous surfaces such as granite, aluminum, glass and ceramics. There are varieties of sizes which can easily be used to customize air bearing systems.

roller air bearings

The roller air bearing is an ultra-Precision, hard install, fixed location bearing to replace your conventional bearings. The result: no friction, no contact, requires no maintenance, indefinite operating life, and no heat generation at high speeds.

flat rectangular air bearings

Flat rectangular air bearings components designed to meet the noncontact requirements at low-cost and high performance. OAV Flat Air Bearings are often used as a standard, off-the-shelf solution for providing axial constraint in rotary motion applications.

air bushing

Air bushing is designed to make air bearings available for use with preexisting designs based on round shaft guides. These components run on standard precision steel. We also provide an option to use Titanium and other special material to maximize stiffness and load capacity.
