Abstract
A side bearing for railroad cars having a body portion of hard elastomeric material and a base for attachment to the truck bolster of a railroad car. The upper bearing surface when the bearing is unloaded is flat, outwardly convex, or outwardly concave, providing the bearing with strain distribution characteristics under load that minimize heat build-up and permanent deformation of the side bearing.
