AIR BEARING

摘要

An aerostatic or aerodynamic bearing comprising a stationary part and a movable part with cooperating bearing surfaces between which there is formed a bearing gap which at one area communicates with an air inlet and at another area opens into the atmosphere. The air inlet comprises one or more filters, and at least one of the bearing surfaces is provided with a pressure-equalizing groove near the area at which the bearing gap opens into the atmosphere.
