ABSTRACT:
A snap-on slide bearing for recessed type guide lugs of unit brake beams for mounting the unit brake beams in their 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 body formed from an ultra high molecular weight polyethylene or other suitable plastic material of dry self lubricating characteristics that is rectilinear in outline and of channel shaped transverse cross-sectional configuration defining a web portion and spaced apart side walls shaped and proportioned for substantially complemental but slidable seating in the side frame guide bracket in which the guide lug is to be mounted, with the inner surfacing of one of the walls of the bearing body being formed to define integral lugs that snap fit into the brake beam guide lug top surface recess for securing the bearing to the guide lug, and when the brake beam is mounted in its operating position in the side frame guide brackets adapted to hold same, dispose the brake beam guide lug in substantial coplanar alignment with the desired brake beam movement radially of the axle wheel to be braked, on actuation of the brakes.
