The rotor () is fixed to a rotor shaft () and is connected non-rotatably to the turbine wheel () and the compressor wheel () via the rotor shaft (). The rotor () is arranged axially between the turbine wheel () and the compressor wheel () on the rotor shaft (). Roller bearings (') are arranged between the rotor () and the turbine wheel () on the one hand and between the rotor () and the compressor wheel () on the other hand. A single separate shaft bearing cassette () with a cassette frame () supports the two roller bearings (′).
