  • Bearing assembly having press-fitted thrust ribs
    Patent number: 3937539
    Abstract: A bearing assembly has a shaft extended through a double cup with opposed tapered raceways machined directly into the cup and shaft. A row of tapered rollers is positioned between each pair of raceways, and the rollers of each row are mounted in opposition and substantially on apex. Expulsion of the rollers is prevented by annular rib rings which are press-fitted over the shaft and embrace the shaft at the large diameter ends of the tapered raceways thereon. The shaft has grooves which underlie the rib rings and enhance the holding power of the rings.
