<p>A gas bearing system comprising two opposing substantially parallel bearing surfaces ( 2, 3 ) and at least one gas duct ( 6 ) for supplying gas through an orifice ( 7 ) to the bearing gap ( 5 ) between the bearing surfaces ( 2, 3 ). At least one of the bearing surfaces ( 2, 3 ) is provided with at least one cavity ( 8, 9 ) extending over 0.3 mm<SUP>2 </SUP>to 3 mm<SUP>2 </SUP>of the at least one bearing surface ( 2, 3 ). The content of the cavity ( 8, 9 ) may be between 0.3 mm<SUP>3 </SUP>and 4 mm<SUP>3</SUP>. The gas duct ( 6 ) may supply gas to the cavity ( 8 ) through an orifice ( 7 ) in the wall of the cavity ( 8 ).</p> |
