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.

A railway truck side-frame pedestal jaw arrangement, said railway truck having a truck longitudinal axis, a first side frame, a second side frame and a bolster, each said first and second side frame having a first longitudinal axis, an upper surface, a lower surface, an outboard surface, an inboard
A railway truck side-frame pedestal jaw arrangement, said railway truck having a truck longitudinal axis, a first side frame, a second side frame and a bolster, each said first and second side frame having a first longitudinal axis, an upper surface, a lower surface, an outboard surface, an inboard surface, a first end, a second end, a longitudinal midpoint between said first and second side-frame ends and, a pedestal jaw at each said side frame first and second end, said railway truck having at least one axle, each said axle having an axle axis generally transverse to said truck longitudinal axis, a first axle end and a second axle end, each said end mountable in a pedestal jaw, a plurality of bearing assemblies, one of said bearing assemblies mountable on each said axle end, a plurality of bearing adapters, one of said bearing adapters mountable in each said pedestal jaw, said bearing assembly and axle end mountable in said pedestal jaw against said adapter for retention in said pedestal jaw, each said pedestal jaw comprising: a pedestal-jaw roof portion, a first side wall portion and a second side wall portion cooperating to define a pedestal jaw cavity, said cavity open at said lower surface, said side-frame inboard surface having at least one stop lug positioned in proximity to said jaw opening, said side-frame outboard surface having at least one stop lug positioned in proximity to said jaw opening, which inboard and outboard stop lugs are substantially aligned; said side-frame longitudinal axis and said axle axis intersecting and being about normal, said axes cooperating to define a horizontal plane; said roof portion at a reference position approximately parallel to said side-frame longitudinal axis and said horizontal plane, said pedestal-jaw first and second side walls approximately normal to said roof portion; each said bearing adapter having at least an upper surface to contact said roof portion, a first side leg and a second side leg to locate said bearing adapter in said jaw opening; said pedestal-jaw opening rotationally displaced about said axle axis to provide said roof portion, said first side wall portion and said second side wall portion at an acute angle of displacement to said horizontal plane; and, said bearing adapter positionable in said angled opening to provide said upper surface and side legs at said acute angle to said horizontal plane from said reference position and operable to receive said axle for transfer of lateral forces from said axle to said stop lugs to inhibit lateral displacement of said side frame and axle to less than one-half degree of angular displacement.
