Air Bearing Bars

  • Air Bearing bars offer a range of advantages over more conventional ways of suspending a substrate or flexible material, these include:
  • Contactless and frictionless, particularly important for sensitive materials that must avoid contact when being processed a long a line
  • Ability to vary the fly height of the material by changing the ratio of air supply vs vacuum
  • Air bearing bars can be easily retrofitted into new and existing designs

Product Description

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