Abstract
A bearing bush, in particular for motor vehicles, includes an inner tube of metal having an outer contour. An intermediate tube of synthetic material rests against the inner tube so as to be slideable at least in a circumferential direction. The intermediate tube has an inner surface being shaped in accordance with the outer contour of the inner tube, and the intermediate tube has an outer surface. A vulcanized layer is applied onto the outer surface of the intermediate tube. A method of manufacturing the bearing bush includes inserting the inner tube and the intermediate tube into a vulcanizing mold together. The intermediate tube is deformed in accordance with an external contour of the inner tube during vulcanization.
