Abstract

A rotor mounting on one end of a shaft, particularly a shaft end of a centrifugal pump unit, in which an adjusting surface and at least one contact surface are constructed on the shaft end, and in which a rotor hub is provided at least on the end facing the shaft with a central bore having an internal thread. The rotor hub is attached to the shaft end by a screw connection. The shaft has a central bore (16) having an internal thread (17) at least on the end facing the rotor hub (12); a threaded pin (18) constructed as a separate component is disposed in both central bores (13, 16) in a connecting, torque-transmitting and force-transmitting manner, and the rotor is aligned on the shaft solely by the adjusting surfaces (20) and contact surfaces (21).
