    Abstract: A bearing bush that can be installed without any auxiliary components and ensures a secure fit has a backing which comprises at least one layer, an overlay (4), on its inner surface and at least one flange (6, 6a, 6b) in the form of a circumferential closed bead provided at a distance from the bush ends. The bearing bush is suitable, inter alia, for flexible joints and pedal bearing systems. The method of producing such a bush takes as its starting point a prefabricated bearing bush (1), the inner surface of the backing (3) of which is exposed in at least one area (5, 5a, 5b) spaced from the bush ends. An internal mandrel is inserted into the bearing bush (1) and the bearing bush is held around its outer surface, at least one gap (23) being left opposite to the exposed area (5, 5a, 5b). The bearing bush is then compressed in the axial direction, the material is thereby displaced into the gap (23, 23′) to form the flange (6).
