Abstract

The invention relates to a bearing unit for a turbocharger rotor. The bearing unit comprises a bearing housing and a bearing bush which is arranged in a central bore for radially mounting a turbocharger rotor in the bearing housing. In the region of a first axial end, the bearing bush has a radially outwardly extending projection. The projection is designed to interact with the bearing housing as an anti-rotation safeguard for the bearing bush.
