A roller bearing assembly including an tapered inner cup (110) defining an inner raceway (118), an tapered outer cup (130) defining an outer raceway (138), the outer raceway having a convex profile, the convex profile being defined by an intersection of the outer raceway and a central plane in which a longitudinal center axis of the roller bearing assembly lies, and a plurality of cylindrical rollers (150) disposed between the tapered inner cup and the tapered outer cup so that each roller is in rolling contact with the inner raceway and the outer raceway, each roller having a first end face (152), a second end face (154) and a cylindrical body extending therebetween.
