Abstract: Radial and thrust bearing system with two hydrostatic bearings axially movable relative to a surrounding bearing housing. Each bearing includes a flange connected to the axle. The flange includes a pressure surface and a collar chamber bearing which has a surface facing the pressure surface and in it a collar groove, the surface and the pressure surface together forming internal and external tightening slots on either side of the collar groove. The pressure surface and the groove together forming a collar chamber to which hydraulic fluid is fed under pressure from a hydraulic fluid source. The collar chamber bearing with the bearing housing form a chamber that is put under hydraulic pressure for pressing the collar chamber bearing against the pressure surface, both collar chamber bearings being pressed in mutually opposite directions.
