Abstract
A railway car truck is provided 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 a bearing assembly. An adapter pad, comprised of a selected hardness elastomer, is fit on top of the bearing adapter. Protrusions extend from the adapter pad and are received in depressions in the bearing adapter to provide longitudinal stability for the adapter pad on the bearing adapter itself.
