A turbocharger bearing is disclosed containing a sleeve (26) which is floatingly disposed in a bore (18) of a bearing case (6) for radially mounting a shaft (14). To prevent rotation of the sleeve an element is disposed in the bearing case (6), which engages both a notch in the sleeve (26) and a recess (48) in the bearing case (6). This arrangement prevents high surface pressures between the element and the sleeve (26) and between the element and the bearing case (6). The element is constructed as a retaining ring (30) having a tongue (48) and at least one boss (54, 56). The tongue (48) engages the recess (46) in the bearing case. The boss (54, 56) is pointed toward the end face (74) of the sleeve (26) where its outside surface (70, 72) contacts at least one surface of the notch (76) formed in the end face (74) of the sleeve (26).
A turbocharger bearing arranged in a bearing case for radially mounting a shaft, said bearing comprising a sleeve which is floatingly disposed in a bore in said bearing case and is secured against axial displacement, and a retaining ring disposed in a ring chamber of the bearing case for securing said sleeve against rotation, wherein said sleeve is provided with a groove and said bearing case is provided with a recess adjacent said ring chamber, and said retaining ring has a tongue which engages in said recess and also has at least one boss that projects toward an axial end face of said sleeve and has an outside surface which contacts at least one surface of said groove.
