  • Method of mounting a spring seat on a hydraulic damping device
    Patent number: 5129137
    Abstract: A spring seat is disposed about a tube which forms part of a shock absorber and supported in a predetermined position thereabout. The tube is subject to press bulge formation so that a portion of the tube becomes force fitted against a portion of the spring seat. Dies can be used to induce the formation of one or more projections which prevent the spring seat from moving axially along the tube. The force fit prevents relative rotation.
