ABSTRACT:
A guide bearing for mounting unit brake beams, for application to railroad car truck side frame unit brake beam guide brackets, in place of the conventional spring steel wear plate now generally used, comprising a one piece body formed from an ultra high molecular weight polymer or other plastic grades of dry self lubricating characteristics that is of elongate trough configuration defining a web portion and spaced apart side walls shaped and proportioned for force fit seating in the guide bracket, with the inner surfacings of the body side walls being formed to closely receive the brake beam guide lug to be mounted in same, to dispose the brake beam guide lug in substantial coplanar alignment with the desired brake beam movement path radially of the axle wheel to be braked, on actuation of the brakes. The inner surfacings of the body walls have a coefficient of friction with respect to steel of about 0.15, and the outer surfacings of the body side walls are coated with a frictional material, such as natural rubber, having a coefficient of friction of about 1.0 relative to steel, for providing effective force fit and frictional retention mounting of the bearing in the bracket. The body includes at the end of same that is to face the axle wheel to be braked a clip arm for force fit application to the bracket end wall for facilitating the anchoring of the bearing to the bracket.
