OAV Air Bearing Bar is produced with profile design for easy retrofitting into existing applications or designing into new applications.
OAV air bearing bar generates evenly distributed gas film between surface and the substrate. Because of low gas viscosity, friction losses by viscous shearing therefore, any mechanical contact is avoided.
Combination of air pressure and vacuum OAV air bearing bar hold substrate down while simultaneously lifting from surface for ultimate precision and fly height. Fly height range of 20 to 120 microns at stability of ±5 microns.
