Abstract
An elastomeric pad is provided for use in a railway car truck that includes two sideframes and a bolster. Each sideframe has a pedestal opening at each end to receive a bearing adapter assembly. The bearing adapter assembly includes a cast steel bearing adapter that is formed to fit on top of an axle bearing assembly. An elastomeric pad, comprised of a selected hardness elastomer, is fit on top of the bearing adapter. Contact buttons extend from the top surface and bottom surface of the elastomeric pad and are received in openings in the elastomeric pad. A conductor provides an electrical connection between the contact buttons.
