OAV aerodynamic foil air bearings provide high-speed, oil-free rotational support using self-generating air films that eliminate mechanical contact, wear, and the need for external lubrication. As rotational speed increases, the compliant foil structure creates a pressurized air layer, enabling true non-contact operation with exceptional efficiency, durability, and reliability.
​
Designed for demanding environments, these bearings operate across a wide range of speeds and temperatures while maintaining stability and low vibration. OAV foil air bearings are ideal for turbomachinery, microturbine generators, aerospace systems, and other high-speed rotating equipment requiring maintenance-free performance.
