Abstract
A side bearing for a railway car wherein spaced, elongated, resilient elastomeric elements bias a unitary friction generating element of the side bearing in operative position, the friction generating element being a separate member which is maintained in frictional engagement with a car body wear plate to provide improvements in the magnitude and uniformity of frictional energy dissipation and to provide, in cooperation with the elastomeric elements, improved bearing performance through the deformation of the elastomeric elements under initial loading and under operating load conditions.
