  • Railcar truck bearing adapter construction
    Patent number: 5572931
    Abstract: An integrally cast bearing adapter arrangement is provided in the pedestal of a railcar truck side frame, which side frame is cast with a pedestal jaw having a roof, and vertical walls of a first and second leg which roof and walls operate as a bearing adapter to receive a bearing assembly for an axle end without introducing the manufacturing and assembly tolerances from discrete component assemblies, thereby avoiding the lateral displacement associated with the added tolerances and operating to minimize angular displacement between each mated axle and side frame.

  • Railcar truck bearing adapter construction
    Patent number: 5509358
    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.
