Abstract

The present invention relates to a hydrodynamic bearing (1) for a rotating rotor shaft (3) of an exhaust-gas turbocharger (2) having at least one cylindrical bearing bush (4), wherein the rotor shaft (3) has, in a region (3a) which is arranged in the bearing bush (4), a cross section (5) deviating from a circular cross section, and wherein a space (6) between the inner periphery (4a) of the bearing bush (4) and the outer periphery (3b) of the rotor shaft (3) is filled with oil.
