This invention relates to an axial bearing system intended for a radially mounted shaft (1) and has two hydrostatic axial bearings (4, 5) capable of axial movement relative to a surrounding bearing housing (3). The bearing system comprises a flange (6, 7) with a pressure surface (6a, 7a) rigidly attached to the shaft (1), at an essentially right angle. An annular chamber bearing (8, 9) has a surface (8a, 9a) facing towards the pressure surface (6a, 7a). In this there is an annular groove (8b, 9b). The surface (8a, 9a) forms together with the pressure surface (6a, 7a) inner and outer sealing gaps to either side of the annular groove. This, together with the pressure surface (6a, 7a), forms an annular chamber (8b, 9b) into which hydraulic fluid is introduced under pressure. The annular chamber bearing (8, 9) together with the bearing housing (3) forms a hydraulically pressurized chamber (15, 16) which forces the annular chamber bearing (8, 9) against the pressure surface (6a, 7a). The two annular chamber bearings (8, 9) are forced in mutually opposing directions in this case. At least one of the flanges (6, 7) is capable of being disassembled from the shaft (1), and in that the pressure surfaces (6a, 7a) face towards one another, that is to say the forces arising from the hydrostatic bearings and acting on the shaft (1) are directed away from one another.
