Abstract

A corrosion resistant cam follower bearing assembly which includes a cam follower shaft, an outer bearing ring disposed about the shaft which defines an inner roller raceway, a sleeve fixedly mounted on the cam follower shaft and defining an inner roller raceway, a plurality of rollers interposed between said raceways, and seals at opposite axial ends of said outer bearing ring for protectively containing the roller elements and raceways. The outer bearing ring and sleeve are formed of heat treated corrosion resistant steel such that the raceways are hardened to at least 58 HRC, the outer bearing ring external exposed surfaces have a chrome plating for improved corrosion resistance in a working environment, and the cam follower shaft which also can be exposed to corrosive contaminants in a working environment is formed of a different and substantially more corrosion resistant material than the material of the sleeve and the outer bearing ring that defines the inner and outer bearing races.
