ABSTRACT:
A snap-on slide bearing for application to U-section formed sheet metal type guide lugs of unit brake beams for mounting the unit brake beams equipped with such guide lugs in the railroad car truck side frame unit brake beam guide brackets, preferably in place of the conventional spring steel wear plate now generally in use, comprising a one piece U-shaped clip member formed from spring steel and defining spaced apart superposed congruently related parallel arms integrally joined at like ends by abridging web, with the arms at their other ends being angled toward each other to define for each such arm a locating stop spaced from the clip member web approximately the length of the the guide lugs, and with the clip member arms each having affixed to the outer surfacing of same a strip that is preferably formed from a polymeric material, such as UHMW polyethylene, which strip is rectilinear and planar in outline, which strips are shaped and proportioned for substantially complemental but slidable seating in the side frame guide bracket in which the guide lug is to be mounted, when the slide bearing is mounted on the guide lug. The slide bearing for each guide lug snap fits thereon from the leading edging of same and extends across the lug to dispose the clip member stops against the guide lug trailing edging.
