WebAir bearings are a type of bearing that use pressurized air to create an air gap between two surfaces. As a result, the bearing surfaces do not contact which eliminates many … A foil bearing, also known as a foil-air bearing, is a type of air bearing. A shaft is supported by a compliant, spring-loaded foil journal lining. Once the shaft is spinning fast enough, the working fluid (usually air) pushes the foil away from the shaft so that no contact occurs. The shaft and foil are separated by the air's … See more Foil bearings were first developed in the late 1950s by AiResearch Mfg.
