A thrust bearing assembly includes upper and lower bearing halves for journaling a shaft therebetween. At least one thrust washer is arranged on the outer surface of at least one of the bearing halves and has ends which extend beyond and confront the ends of the bearing half on which the thrust washer is mounted to support it against rotational movement relative to the bearing half. A bearing half can have such thrust washers, in which case the other bearing half is narrower and is retained axially by the ends of the thrust washers of the opposing bearing half, or a thrust bearing can be provided on each of the bearing halves in axially opposed relation to one another.
