Abstract

A turbocharger device for an internal combustion engine and a method for mounting a turbocharger device are described. The turbocharger device has a housing with a locating hole, in which a turbocharger shaft is mounted by two rolling element bearings. A rolling element bearing sleeve is situated between the two rolling element bearings. The rolling element bearing sleeve and hence the two rolling element bearings are fixed with the turbocharger shaft in the axial direction with the aid of two pins, which are introduced through a hole in the housing and are pressed into a groove in the rolling element bearing sleeve. During this process, the beveled tips of the pins slide along the chamfered outer edges of the groove as far as an end position, which fixes the axial position of the rolling element bearing sleeve.
