Abstract
A method for mounting a rolling bearing arrangement onto a rotor and into the bearing housing of a turbocharger is provided. The method includes inserting a component, which is deformable under the exertion of pressure, into the intermediate space between two rolling bearings of the rotor assembly. The rotor assembly includes a rotor shaft, inner bearing rings which are fastened to the rotor shaft or integrated into the rotor shaft and which have a spacing to one another, rolling elements which are inserted into the inner bearing rings, and outer bearing rings which likewise have a spacing to one another. The method also includes deforming, by exertion of pressure, the component that has been inserted into the intermediate space between the two rolling bearings, to set a desired axial preload between the two rolling bearings.
