ABSTRACT:
A self lubricating liner for railroad car center plate assemblies comprising a bowl shaped member formed from an ultra high molecular weight polymer of dry self lubricating characteristics and shaped to define a floor portion and an upstanding side wall. The liner is stretch resistant and is received within the trunk bolster bowl on the floor of the bowl, it being proportioned to be fit on the bolster center plate and to entirely fill the space between the truck bolster bowl and the body bolster center plate 360.degree. about the side wall of the bowl to preclude high energy impacts between these parts when coupler impacts and train line action are occasioned. The liner side wall is formed to be spaced from the top surfacing of the bowl side wall and make a tight seal about the neck of the bolster center plate. In use, the liner effects resurfacing action on the surfaces engaging same to make them effectively resistant against wear.
