A method of creating a roller bearing, comprising re-shaping a bearing ring blank utilizing cold impact intrusion, wherein the bearing ring blank includes a surface profile that forms at least one contour section within a contact side of the bearing ring upon the re-shaping, and wherein the contact side is configured to contact a support structure.

Method for non-cutting manufacturing of a bearing ring for a rolling bearing and rolling bearing comprising the bearing ring

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.

Method for producing an inner ring for a tapered roller bearing, and tapered roller bearing having an inner ring

Bearing assemblies, such as angular contact bearing assemblies, and methods of producing the same are disclosed. One angular contact ball bearing may include an inner ring and an outer ring, the inner ring having an outer raceway and the outer ring having an inner raceway. A plurality rolling elements may be arranged between the outer raceway and the inner raceway. The outer raceway may be formed by an extrusion of the inner ring and/or the inner raceway may be formed by an extrusion of the outer ring. The raceways may be extruded in their final contour, without any cutting.

Angular contact ball bearing having a cold-formed bearing ring, and a method for manufacturing a bearing ring of said angular contact ball bearing

A planetary gear () such as a differential gear, with a planetary carrier () on which planetary wheels () are rotatively connected, with at least one sun gear () in meshing engagement, whereby the planetary carrier () can be connected to a drive wheel () such as a spur wheel (), whereby further comprising a rolling bearing () having an inner bearing ring () and an outer bearing ring () for the axial and/or radial positioning of the planetary carrier () with respect to a fixed housing such as a gear housing, characterized in that an outer bearing ring () between the inner bearing ring () and the planetary support () is forced as far as a seating region radially inwards of the planetary carrier () for connection to the planetary carrier ().
