Abstract
A side frame for a railway car is disclosed comprising a pedestal jaw and an integral crown shaped pedestal jaw roof. A liner matching the shape of the crowned pedestal jaw roof is removably mounted to the pedestal jaw roof. In operation, the crown shaped pedestal jaw roof and snap-on liner reduce wear on the pedestal jaw roof and permit swinging of the side frames relative to the railcar axles. The integral crown shaped pedestal roof and snap-on liner eliminate the traditional rocker seat, shims, and welded retainers, thereby reducing the maintenance and cost of traditional side frames.
