The auxiliary thrust bearing comprises a ball (54) determining the axial free movement of a rotor. This is under a small load in the opposite direction to that on the main bearing (9). The ball fits between the end face (23) of an adjusting screw (53) concentric to the rotor and a face (52) rotating with the latter. The face is pref. contained inside a bore (51) in the rotor, into which the screw extends. |
