ABSTRACT:
A railcar truck, bearing-adapter assembly for an axle end has vertically extending arms to securely capture and maintain a roller bearing and axle end assembly at about an as-assembled reference position within the adapter assembly and sideframe pedestal jaw, where the as-assembled reference position has the railcar truck side frames about parallel and the axles about normal to the side frames, and which adapter assemblies in the opposed sideframe pedestal jaw are secured within a cross-passage at the ends of the truck side frames to capture and retain the axle ends in opposing side-frame pedestal jaws at about the reference as-assembled position to inhibit both horizontal and vertical axle displacement truck and thus minimize railcar truck warping.
