Abstract

A bearing unit for a turbocharger, including a bearing housing which extends in an axial direction, a bearing cartridge, situated within the bearing housing, having an outer bearing ring, and a securing element, situated on the bearing housing, for the twist-free positioning of the outer bearing ring within the bearing housing. The sum of the forces acting on the outer bearing ring is essentially zero. A bearing unit of this type prevents twisting of the outer bearing ring without reducing the vibration-damping effect of the quenching oil film.
