Abstract

The invention relates to a gas bearing-mounted arrangement of bodies, which can be displaced relative to one another, with an inner body (1; 101; 201; 301; 401) having a bearing surface (14'; 114'; 214'; 314'; 414') that, at least in sections, extends in a curved manner, and with an outer body (3; 203; 303; 403), which at least partially surrounds at least the curved section of the bearing surface (14'; 114'; 214'; 314'; 414') of the inner body (1; 101; 201; 301; 401). The inner body (1; 101; 201; 301; 401) is, in its bearing surface (14'; 114'; 214'; 314'; 414'), provided, at least in areas, with microholes (140, 141, 142, 143; 140'; 240; 350, 351, 352, 353; 450, 451, 452, 453), which define a gas bearing between the inner body (1; 101; 201; 301; 401) and the outer body (3; 203; 303; 403), these microholes (140, 141, 142, 143; 140'; 240; 350, 351, 352, 353; 450, 451, 452, 453) leading into a gas supply structure of the inner body (1; 101; 201; 301; 401). The invention is characterized in that the microholes (140, 141, 142, 143; 140'; 240; 350, 351, 352, 353; 450, 451, 452, 453) are made in the inner body (1; 101; 201; 301; 401) starting from the side of the bearing surface (14'; 114'; 214'; 314'; 414').
