The invention relates to a radial bearing arrangement (110) of an exhaust gas turbocharger (100) for mounting a shaft (120) in a bearing housing (130). The radial bearing arrangement (110) comprises a radial bearing bush (140) which is arranged between the shaft (120) and the bearing housing (130), wherein the radial bearing bush (140) comprises a radially outwardly projecting collar (141) which interacts in the axial direction with an axial stop (131) on the bearing housing (130). The geometry of the radially outwardly projecting collar (141) is interrupted by way of cut-outs, with the result that a force which acts on the collar (141) as a result of an oil feed pressure is minimized, and wherein the radial bearing bush (140) is configured in such a way that a lubricating film can be formed between an end surface of the radial bearing bush (140) and a counterpiece (160) which is arranged on the shaft (120). 本发明涉及一种用于将轴(120)支承在轴承壳体(130)中的废气涡轮增压器(100)的径向轴承组件(110)。径向轴承组件包括布置在轴(120)与轴承壳体(130)之间的径向轴承衬套(140)，其中，径向
