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.

Bearing bush and method of manufacturing the bearing bush

An elastic bearing bush includes an outer, cylindrical bearing sleeve having an interior, an inner part, and a horizontally extending elastomer body holding the inner part in the interior. The elastomer body defines free regions in the form of circular segments acting as upper and lower fluid-filled spring deflection chambers above and below the inner part. Elastic, substantially cup-shaped stops are fixed on the bearing sleeve, are disposed inside the spring deflection chambers, protrude to the vicinity of the inner part and enclose the spring deflection chambers between the stops and the bearing sleeve. The spring deflection chambers communicate with one another through conduits.
