<p>A railway car truck (10) is provided that includes two sideframes (14) and a bolster (12). 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 (30) that is formed to fit on top of a bearing assembly. An adapter pad (32), comprised of a selected hardness elastomer, is fit on top of the bearing adapter. Protrusions (64, 66) extend from the adapter pad and are received in depressions (48, 49) in the bearing adapter (30) to provide longitudinal stability for the adapter pad on the bearing adapter itself.</p> |
