ABSTRACT:
A railcar truck side frame has a pedestal jaw arrangement, which inclines the bearing adapter for the axle and bearing assembly with a relative slope in the side-frame longitudinal direction, to provide transfer of the forces causing angular displacement of the axle to stop lugs on the side-frame outer surface and to minimize axle angular displacement and, consequently, truck warping and hunting.
