Abstract of the Disclosure A bolster for carrying a car body rests transversely on a pair of side frames of a truck. A side bearer and wear plate assembly are disposed between the ends of the bolster and the side frames to permit the bolster to be rotated relatively about small angles with respect to the side frames. The side bearers each comprise a body having relatively low friction surfaces in engagement with the wear plates. Each of the low friction surfaces may include two or more parallel arcuate tracks or segments which may have radii corresponding to the directions of angular rotation movements of the bolster. The total surface area of the low friction surfaces is designed for optimum operation for predetermined load conditions.
