The invention relates to a bearing assembly for an exhaust gas turbocharger for rotatably supporting a rotor shaft on a bearing housing, having at least one bearing outer ring of a radial bearing, which at least one bearing outer ring is placed in a bearing bore of the bearing housing and consists of at least one part, and at least one securing element, which consists of at least one part and by which the bearing outer ring is axially fastened in relation to the bearing housing. In order to simplify the assembly of a corresponding bearing assembly and to reduce the production costs thereof, at least one circumferential groove, according to the invention, is arranged on an outer lateral surface of a compressor-side end section of the bearing outer ring, in which at least one groove the securing element engages, and the securing element is arranged outside of the bearing bore on the compressor side and is supported at least indirectly on a compressor-side end of the bearing housing.
A bearing arrangement for an exhaust gas turbocharger for rotating support of a rotor on a bearing housing, comprising at least one bearing outer ring of a radial bearing, said at least one outer bearing ring being constructed in two parts and placed in a bearing hole of the bearing housing, at least one securing element constructed at least in one part that fixes the bearing outer ring axially relative to the bearing housing, at least one groove arranged on an outer lateral surface of a compressor-side end section of the bearing outer ring in which the securing element engages, wherein the securing element is arranged on a compressor side outside of the bearing hole and is supported at least indirectly on a compressor-side end of the bearing housing, the two parts of the bearing outer ring comprise a compressor-side outer ring part and a turbine-side outer ring part, the compressor-side end section of the bearing outer ring is arranged on the compressor-side outer ring part, and the outer ring parts are guided for axial movement relative to each other and are pretensioned by at least one intermediate compression spring in axially opposite directions.
