  • Strut swedge tooling
    Patent number: 8025133
    Abstract: A railroad freight car brake beam strut assembly including an elongated strut having first and second joined walls. Each wall of the strut defines a bore opening to a hollow center portion and to an exterior of the strut. The bores defined by the walls on the strut accommodate a brake lever pivot pin extending through strut thereby connecting the brake lever to the strut and so as to allow pivoting of the brake lever. Each bore defined by the walls of the strut has a closed marginal edge. One brake pin bushing is accommodated in each bore defined by the strut so as to journal a lengthwise portion of the brake lever pivot pin.
