Claim 0:
1. A railroad car brake beam wear guide, comprising:
a first wall;
a second wall spaced apart from the first wall;
an end wall monolithically formed with and connecting the first wall and the second wall, wherein the first wall and the second wall with the end wall therebetween form a U-shape extending longitudinally from a front of the wear guide to a back of the wear guide;
a polymer spacer integrally attached to an interior surface of the end wall, wherein the first wall, the second wall, and the spacer define a slide-way configured to permit movement of a lug of a brake beam in the slide-way, wherein the spacer is configured to limit lateral movement of the brake beam, and wherein an end wall thickness and a spacer thickness combine to provide a spacer and end wall combined thickness that is uniform extending longitudinally from the front of the wear guide to the back of the wear guide;
a first gap between the first wall and the spacer, the first gap extending away from a first gap bottom at the interior surface of the end wall to a first gap height such that the spacer is not in contact with the first wall; and
a second gap between the second wall and the spacer, the second gap extending away from a second gap bottom at the interior surface of the end wall to a second gap height such that the spacer is not in contact with the second wall, wherein the first gap bottom and the second gap bottom each extend longitudinally from the front of the wear guide to the back of the wear guide, and wherein the first gap bottom and the second gap bottom each extend longitudinally parallel to a bottom surface of the end wall that is opposite the interior surface of the end wall and that extends longitudinally from the front of the wear guide to the back of the wear guide.
