ABSTRACT:
A railway car truck includes side frames each having a pedestal formed on longitudinally opposite ends thereof. Each pedestal has an upper jaw and a lower jaw surrounding a pedestal opening. The upper jaw has a roof section above the pedestal opening and the lower jaw has an inner wall and an outer wall on opposite sides of the pedestal opening. The inner and outer walls are spaced apart from one another to define a wide pedestal opening. A bearing adapter is received in each pedestal opening. Each bearing adapter includes a concave opening to receive a bearing and a generally rectangular center section having a top surface generally opposite the concave opening. The bearing adapter has steps extending outward from sides thereof that have outer surfaces separated by a distance corresponding to the width of the pedestal opening. The railway car truck also includes an elastomeric adapter pad mounted on top of the bearing adapter that has a generally flat, generally rectangular top section and depending legs that extend along the outer surfaces of the steps. The top section defines a pad for engaging the roof section. The depending legs define pads for engaging the inner and outer walls.
