Vacuum Preloaded Air Bearings

 

Using a combination of air pressure and vacuum, New Way VPL air bearings hold themselves down while simultaneously lifting themselves from a guide surface. By adjusting the vacuum and the pressure separately, the fly height and stiffness of these vacuum preloaded air bearings can be optimized.
