Zusammenfassung:	Tapered roller bearings and methods of producing the same are disclosed. One method is for producing an inner ring for a tapered roller bearing in which the inner ring comprises a raceway portion and a fixed edge portion. The method may include providing an inner ring blank and an unfinished fixed edge portion. The inner ring blank may include an unfinished raceway portion and the unfinished fixed edge portion may have a larger outside diameter than the unfinished raceway portion. The inner ring blank may have a through-opening. The inner ring blank may be formed into the inner ring by extrusion in a main forming step, the unfinished fixed edge portion being transformed into the fixed edge portion and the unfinished raceway portion being transformed into the raceway portion. The inner ring may be formed in its final contour without any cutting.
