  • Flange sleeve and method for the production thereof
    Patent number: 7534044
    Abstract: The invention relates to a method for the production of a flange sleeve especially for a sliding bearing. A strip of material is cut into lengths corresponding to the later periphery of the flange sleeve. The strip section thus arising is rolled to form a hollow cylindrical sleeve with an open butt joint and a collar is placed around one or two sides. The open butt joint is expanded in the region of the collar to form a V-shaped slit. One or several recesses are made in the region of the later open butt joint on one or two of the longitudinal edges of the strip section.

  • Roll-formed bushing for sliding surface bearings
    Patent number: 4865467
    Abstract: A roll-formed bushing for sliding surface bearings has no machining allowance in the bearing bore and is made of a strip section and has a butt joint that extends throughout the width of the bearing. In order to reduce the allowances of the bore diameter and the outside diameter of the bearing bushing, the butt joint has been closed by charge carrier beam welding.
