Flat Round Air Bearings

High-Precision Flat Round Air Bearings for Frictionless Motion

OAV flat round air bearings provide ultra-precise, frictionless motion using our GraphAir™ film technology. By creating a thin, pressurized air layer between surfaces, they eliminate mechanical contact, reduce wear, and deliver exceptional stability and repeatability for high-performance motion systems.

​

Designed for use on flat, non-porous surfaces such as granite, aluminum, glass, and ceramic, these bearings are ideal for semiconductor manufacturing, precision metrology, and advanced automation. OAV flat round air bearings support both linear and rotary motion applications while maintaining tight geometric control and long service life. Multiple sizes and custom configurations are available to meet specific engineering requirements.

Precision Motion With GraphAir™ Technology

Porous GraphAir™ technology forms a uniform, pressurized air film across a circular surface, enabling frictionless, non-contact motion with perfectly balanced pressure distribution. The round geometry provides inherent symmetry, making these bearings ideal for rotary positioning, precision alignment, and applications requiring consistent stiffness in all directions.
