A bearing arrangement has fluid pressure bearings which permit an especially stiff support and is therefore especially well suited for high precision machines such as coordinate measuring apparatus. The bearing arrangement includes at least two fluid pressure bearings (12, 13, 14, 15, 16, 17) having
A bearing arrangement has fluid pressure bearings which permit an especially stiff support and is therefore especially well suited for high precision machines such as coordinate measuring apparatus. The bearing arrangement includes at least two fluid pressure bearings (12, 13, 14, 15, 16, 17) having a membrane formed as a support end. The membrane is concavely deformed by the bearing pressure. The bearing arrangement also includes a rigidly configured bearing base body which is supported on the two fluid pressure bearings. The rigid support is achieved in that at least one of the fluid pressure bearings includes a bearing housing (12a, 12b; 13a, 13b; 14a, 14b) which is configured as one piece and in that the bearing base body (6) is operatively connected directly to the bearing housing (12a, 12b; 13a, 13b; 14a, 14b). The bearing housing includes at least the membrane.
