Abstract
A radial bearing arrangement of an exhaust gas turbocharger for mounting a shaft in a bearing housing is disclosed. The radial bearing arrangement comprises a radial bearing bush arranged between the shaft and the bearing housing, wherein the radial bearing bush features a radially outwardly projecting collar, which interacts in the axial direction with an axial stop on the bearing housing. The geometry of the radially outwardly projecting collar is interrupted by cut-outs, such that a force acting on the collar as a result of an oil feed pressure is minimized, and wherein the radial bearing bush is configured such that a lubricating film can form between an end surface of the radial bearing bush and a counterpiece arranged on the shaft.
