ABSTRACT:
An improved double row tapered bearing assembly for use on rail cars employs a shortened journal in combination with a seal wear ring having an inner surface in interference fitting relation with the journal and an outer surface having a diameter at least equal to the mean diameter of the inner raceways. The wear ring and backing ring cooperate to provide an increased journal and bearing assembly section modulus and rigidity to thereby reduce flexing and the consequent journal fretting and component end face wear.
