Abstract

SIDE BEARING UNIT FOR RAILROAD CAR ABSTRACT A side bearing unit for attachment to a bolster of a truck of a railroad car has a base which may be fastened to a top wall of the bolster. A housing, car-ried by the base, includes spaced sidewalls joined by end walls to define a cavity for an elastomeric device. A cap, positioned within the housing, is integrally joined to the elastomeric device with a top surface of the cap located above the housing for engagement with a wear plate attached to a bottom of a body of the car. During travel of the railroad car, sets of side bearing unit are particularly effective in regulating indepen-dent rolling of the car body as well as impeding truck hunting, for example.
