ABSTRACT:
A constant contact resilient side bearing adapted to be positioned on a railroad car truck bolster and in constant contact with the underside of the car body for retarding movement of the car truck relative to the car body includes a housing adapted to be positioned on the bolster and which may, in some applications, be integrally cast with the bolster. A pair of rollers are mounted within the housing for contact with the underside of a car body, the rollers being arranged with their axes approximately parallel to the longitudinal axis of the bolster or generally having the roller axes intersect in the center of the center plate. A resilient elastomeric pad is positioned within the housing and beneath the rollers. The pad provides resistance to movement of the rollers responsive to relative rotation between the car truck bolster and car body underside.
