ABSTRACT:
A bolster bearing having a flat bottom wall and an annular sidewall is disposed in the bolster bowl of a truck bolster, a radially extending annular flange on the bearing sidewall overlying an upper surface of the upstanding rim of the truck bolster defining its bolster bowl. Cooperating elements on the rim and on the bearing flange prevent rotation of the bearing from a first position relative to the bolster bowl. The bearing may be radially shifted from its first position to a second position upon disengagement of such elements followed by a reengagement of such elements at such second position in which the bearing is likewise prevented from rotation relative to the bolster bowl.
