Adapter Plus Steering Pad System

The patented elastomer pedestal pad-liner-bearing adapter design improves axle-to-rail wheelset alignment. Unlike conventional adapters, which are all iron, the elastomer pad allows controlled motion of the wheelset lowering forces in a curve. Adapter Plus improves curving and rolling resistance and reduces wear on the sideframe pedestal roof, thrust lug, bearing adapter crown and the bearing adapter thrust lug area.
