ABSTRACT:
A bearing for an exhaust-gas turbocharger including a sleeve 26 which is arranged in a bore 36 of a bearing housing 6 and which is prevented from rotating. The sleeve 26 contains, at each of its two axial end regions, an inner and an outer bearing face 34, 32 and at least two openings 28 between the end regions. Sleeve rotation is prevented in a functionally reliable manner and at a low construction cost by a preferably annular spring element 50 which is elastic in the circumferential direction and which engages by means of a axially bent first end 52 in a groove 54 in the sleeve 26. The bearing housing 6 has a recess 56 which opens into the bore of the bearing housing radially relative to the shaft 14 and in which the radially outwardly bent second end 58 of the spring element 50 engages.
