Claim 2:
3. A roller bearing assembly, comprising
an inner cup defining a tapered inner raceway having a concave profile, the concave profile defined by an intersection of the central plane and the inner raceway;
an outer cup defining a tapered outer raceway, the tapered outer raceway having a convex profile, the convex profile being defined by an intersection of the outer tapered raceway and a central plane in which a longitudinal center axis of the roller bearing assembly lies, the outer and inner cups being concentric about the longitudinal center axis;
a roller retainer having an inner perimeter, an outer perimeter and a frustoconically shaped body extending therebetween, the body defining a plurality of roller pockets; and
a plurality of straight rollers disposed between the tapered inner cup and the tapered outer cup, each straight roller being disposed in a corresponding roller pocket of the roller retainer so that each straight roller is in rolling contact with the inner tapered raceway and the outer tapered raceway, each straight roller having a first end face, a second end face and a cylindrical body extending therebetween,
wherein each roller pocket is symmetrical and has a maximum width that is greater than a maximum width of each corresponding straight roller 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.
