A hydrostatic bearing having a bearing body positioned between a first and a second part displaceable relative to each other. A guideway is mounted on the second part. The bearing body for the displacement of the first part relative to the second part in a direction perpendicular to the guideway has a piston displaceable in a direction perpendicular to the guideway. Regulating means is provided for regulating the position of the first part with respect to the second part in a direction perpendicular to the guideway in accordance with a predetermined value. A chamber is formed between the bearing body and a part containing a recess and a pipe for pressurized fluid extends to the chamber. The bearing body has on its side opposite the chamber support recesses for supporting the bearing body and bores in the bearing body connect said last named recesses to the chamber. The bearing body has a circular support surface in which the support recesses are each distributed in a quadrant of the circular support surface, and a throttle is connected to the support recesses. The throttle is a screw-threaded bolt screwed into a threaded bore, through the screw thread of which pressurized fluid flows to the support recesses.
