The invention relates to a hydrodynamic brake with a rotor comprising a rotor blade wheel and with a stator comprising a stator blade wheel, the rotor blade wheel and the stator blade wheel, together, forming a working space that can be filled with a working medium for transmitting driving power from the rotor to the stator. The rotor comprises a rotor shaft, which supports the rotor blade wheel and which is rotationally mounted by means of a bearing having at least two or exactly two antifriction bearings.; The invention is characterized by the following features: the bearing of the rotor shaft comprises a first antifriction bearing that can absorb a predetermined first axial force and further comprises a second antifriction bearing, which is arranged in an axially lateral manner with regard to the first antifriction bearing and which can absorb a predetermined second axial force, the second axial force being greater than the first axial force, and the rotor blade wheel is arranged laterally opposite the stator blade wheel on the same axial side as the first antifriction bearing opposite the second antifriction bearing so that an axial force from the rotor blade wheel toward the stator blade wheel is absorbed by the second antifriction bearing.
