The aim of the invention is to improve a belt tensioner for a belt drive of an internal combustion engine, having a central bearing device which serves to define a pivot axis for the belt tensioning arm, and having a bearing sleeve which is connected to the tensioning arm, wherein the bearing device extends through the bearing sleeve and the bearing sleeve is mounted in a friction-damping manner by means of a plain bearing arrangement, so as to be pivotable about the bearing device, with said improvement being such that a good function of the belt tensioner is maintained despite a simplification of the design and a reduction in differently designed parts. Said problem is solved by means of a generic belt tensioner for a belt drive of an internal combustion engine, in which the plain bearing arrangement has at least two opposite sliding faces which have the same material.
