Abstract
A side bearing for a railway car having a pair of spaced elongated resilient elastomeric elements which bias the elements of the side bearing in operative position and which elements preferably have uppermost separate members which are effective for generating increased frictional dissipation of energy over the frictional energy dissipation available with an elastomeric element only and for providing, in cooperation with the elastomeric elements, improved bearing performance through the deformation of the elastomeric elements under initial loading and under operating loads.
