<p>The invention relates to a gas bearing with a bearing surface arranged on a gas permeable element to which a pressure medium can be supplied from an external source. The bearing surface is arranged on a less permeable surface layer, through which holes are made. In order to ensure good gas flow through the holes, the holes extend into the porous material a distance corresponding to at least half the diameter of the holes, and those portions of the holes which are situated inside said surface layer are limited by porous material.</p> |
