In a rotor mast for a rotorcraft, the rotor mast can be coupled in a rotationally fixed manner to a drive unit of a helicopter rotor transmission, which allows a particularly smooth running operation. This is achieved in that the rotor mast is configured in two parts, and comprises a bearing mast and an outer mast, with the outer mast, configured as a hollow body, is mounted, concentrically surrounding the bearing mast, such that it can rotate about a central axis relative to the bearing mast. The outer mast can be operatively connected with the helicopter rotor transmission, and the bearing mast can be mounted in the rotorcraft in a locationally and rotationally fixed manner, such that the outer mast can be coupled with a main rotor in a rotationally fixed manner, and can be set in rotation with the helicopter rotor transmission.
