The auxiliary bearing comprises a chromium steel rotor (2) mounted on the rotary shaft (1), a graphite stator (3) mounted on the frame (5) and disposed to face the rotor (2) and to leave clearance relative thereto which is narrower than the air gap in the magnetic bearings which constitute the main supports of the rotary shaft, a network (4) of liquid feed channels opening out into the empty space between the rotor (2) and the stator (3), and selective control means for controlling the supply of liquid through said network of feed channels. The auxiliary bearing may be of the radial clearance type or of the axial clearance type.
