A railway vehicle side bearing has a housing adapted to be affixed to a railway vehicle truck intermediate the truck and a car body wear plate. The housing has side and end walls enclosing a cavity adapted to receive a compliant elastomeric bearing having an upper end portion thereof extending vertically above the side and end walls. A rigid spacer has an upstanding abutment portion disposed adjacent the upstanding elastomeric bearing and an upwardly facing surface adjacent the abutment portion. A rigid bearing is supported on that surface for movement thereon between limits, the spacer and the rigid bearing having an overall vertical height that, when supported on that surface with the spacer disposed within the cavity the rigid bearing has an uppermost extent located above the highest elevation of the housing walls for contacting the wear plate so as to limit the vertically downward travel of the wear plate towards the side bearing. The abutment portion extends vertically upward to an elevation sufficient to laterally confine a vertical extent of the elastomeric bearing extending intermediate the uppermost extent of the rigid bearing and the highest elevation of the housing walls for limiting movement of the vertical extent in at least one lateral direction throughout deformation of the elastomeric bearing in vertical compression.
