Claim 0:
1. A roller bearing assembly comprising:
a tapered inner cup defining an inner raceway having a concave profile, the concave profile defined by an intersection of the central plane and the inner raceway;
a tapered outer cup defining an outer raceway, 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, the tapered outer and inner cups being concentric about the longitudinal center axis;
a plurality of straight rollers disposed between the tapered inner cup and the tapered outer cup so that each straight roller is in rolling contact with the inner raceway and the outer raceway, each straight roller having a first end face, a second end face and a cylindrical body extending therebetween; and
a roller retainer defining a plurality of roller pockets, each roller pocket receiving a corresponding straight roller, and each roller pocket being symmetrical and having dimensions so that each straight roller is limitedly rotatable in both directions about a pivot axis that intersects the longitudinal center axis of the roller bearing assembly and a midpoint of the longitudinal center axis of the corresponding straight roller, wherein the pivot axis is transverse to the longitudinal center axis of the corresponding straight roller.
