Abstract
The invention relates to a turbocharger comprising an exhaust gas turbine a fresh air compressor and a bearing seat in which the rotor shaft that is equipped with the turbine and the compressor wheel is rotatably mounted by means of at least one radial bearing. The radial bearing is designed as a floating bush bearing with a hollow cylindrical floating bush body positioned between a bearing seat of the bearing housing and the rotor shaft said body being provided with a defined imbalance in order to counteract an imbalance of the turbo rotor.
