ABSTRACT:
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).
