Abstract

A rubber-metal bush bearing, in particular a control arm bearing for a motor vehicle wheel suspension, including a metal inner part, an elastomer body arranged radially relative to the inner part and a metal outer bush, wherein the elastomer body is fixed to the inner part and to the outer bush in material-bonded relationship and wherein the outer bush is for fixing in an associated bearing eye of an arm and the inner part has at both sides in terminal relationship a respective flat flange portion for fixing to a component. The inner part is an extruded hollow-chamber profile member which is cut to length and which at both longitudinal ends is transformed in terminal relationship into the respective flat flange portion in such a way that oppositely disposed wall portions of the hollow-chamber profile member are brought into mutual surface contact.
