ABSTRACT:
A corrosion-resistant bearing assembly comprising inner and outer bearing races with a plurality of roller elements interposed therebetween. The inner and outer bearing races each have a bi-metallic construction which includes an outer body portion formed of a corrosion-resistant metal alloy, such as stainless steel, and a roller raceway defining insert formed of hardened, high-carbon steel. The bearing races, thereby, are substantially resistant to corrosive effects of contaminants in the outside environment, while providing hardened raceways for long-term bearing life.
