PI (Physik Instrumente) L.P. Vacuum Preloaded Flat Pad Air Bearing

When flat pad air bearings are used in lightly loaded applications, it is common to use a vacuum preload. A vacuum preload allows the bearing to operate closer to its design loading and therefore optimal stiffness is obtained. Vacuum preload also allows the bearing to resist light pull forces. Any flat pad air bearing can be modified for vacuum preloading and tailored to your exact application.
