ABSTRACT:
A rubber-metal bushing includes a seamless inner metal DOM tube surrounded by an elastomer cylinder. A flanged ferrule is press fit into one or both ends of the tube so that the flange engages an end portion of the cylinder. The bushing is cost reduced by replacing the DOM tube with a seamed tube formed from flat stock. An adhesive at the tube-ferrule interface maintains the two elements together.
