A sheet metal strip configured for use as an inner or outer raceway of a rolling-element bearing, and a method of forming the raceway by punching and/or laser cutting a strip of material from a metal sheet, bending the sheet into a ring and welding the ends of the strip together, and mounting the strip on a circular inner or outer surface to form an outer or inner raceway.

Annular joint surfaces of a lower case of a strut bearing device respectively have case-side projections that project in an axial direction. Shapes A of the case-side projections, seen in an axial direction, continue in a circumferential direction, and vary their position in a radial direction along the circumferential direction. An inner-diameter side seal has a seal-side recess fitted to the case-side projection. An outer-diameter side seal has a seal-side recess fitted to the case-side projection.

Wheel hubs for a motor-vehicle wheel hub assemblies provided with a bearing unit in turn which include at least one row of rolling bodies, the wheel hub being provided with at least two sheet-metal elements which are rigidly joined together, wherein a first sheet-metal element forms a raceway for the at least one row of rolling bodies.

A turbocharger includes a turbine, a compressor, and a bearing housing forming a bearing bore. A bearing arrangement is disposed between a shaft interconnecting the turbine and compressor wheels, and the bearing housing. The bearing arrangement includes first and second bearings formed between an outer bearing race element disposed within the bearing bore an inner bearing race element disposed within the outer bearing race element and between the outer bearing race element and the shaft. The inner bearing race element includes a flared portion extending radially outwardly to provide torsional and bending rigidity to the shaft.

A steering bearing for bearing a steering column of a motor vehicle, including an inner ring and an outer ring having respective raceways on which balls roll, the outer ring being enclosed by a sleeve in which a spring ring is arranged. The spring ring tensions the balls against the respective raceways and the balls roll on said spring ring.

A wave generator of a strain wave gearing has a rigid plug provided with an elliptical outer peripheral surface, and a roller bearing. The outer peripheral surface of the plug is provided with a major-axis-side outer-peripheral surface portion formed at a major axis position L1, and a minor-axis-side outer-peripheral surface portion formed at a minor axis position L2. The major-axis-side outer-peripheral surface portion is a tapered surface that is tapered along a center axis line, and the minor-axis-side outer-peripheral surface portion is an inverted tapered surface that is tapered in the opposite direction. An externally toothed gear can be supported and flexed into an elliptical shape without partial contact by using the wave generator in which the roller bearing is used.

A pivot cradle bearing (1) having a pivoting element (2) which is mounted to pivot in a housing (3) is provided in which an inner bearing shell (7), on which rolling bodies (4) are rolling, is held on the pivoting element (2). The inner bearing shell (7) is held by rivets (10) in a form-fitting manner on the pivoting element (2) in the circumferential direction of the bearing shell (7).

Wheel hubs for a motor-vehicle wheel hub assemblies provided with a bearing unit in turn which include at least one row of rolling bodies, the wheel hub being provided with at least two sheet-metal elements which are rigidly joined together, wherein a first sheet-metal element forms a raceway for the at least one row of rolling bodies.

A raceway element for a rolling-element bearing, the rolling-element bearing having an inner ring, an outer ring, and a plurality of rolling elements that are disposed between the inner ring and the outer ring. The raceway element is configured as an inner ring or as an outer ring, or is configured to be attachable to an inner ring or outer ring of the bearing, wherein at least one surface of the raceway element is configured as a raceway for the rolling elements. The raceway element is formed from a sheet metal panel having at least one recess formed in the surface configured as the raceway.

A raceway element for a rolling-element bearing having an inner ring, an outer ring, and a plurality of rolling elements disposed between the inner ring and the outer ring, the raceway element being configured as the inner ring of the bearing or as the outer ring of the bearing, or being configured to be attachable to an inner ring or outer ring of the bearing. At least one surface of the raceway element is configured as a raceway for the rolling elements, the raceway element is formed from a sheet metal panel, and the raceway element includes a flange for guiding the rolling elements formed one-piece with the raceway element. Also, a bearing including the element and a method of forming the element.
