Patent number: 8398311Abstract: A bearing assembly comprises at least two adjacently-disposed bearings. Each bearing includes a bearing outer ring having a cylindrical outer circumferential surface. A bearing support retains the at least two bearings such that respective rotational axes of the at least two bearings extend in parallel. A spacer has at least two cylindrical openings configured to receive the respective cylindrical outer circumferential surfaces of the bearing outer rings such that a circumferential inner surface of each opening covers at least a portion of a width of the bearing outer ring received therein and surrounds an entire circumference of the bearing outer ring received therein. The bearing support is not fixedly connected to the spacer.Type: GrantFiled: September 1, 2009Date of Patent: March 19, 2013Assignee: Aktiebolaget SKFInventors: Berthold Beyfuss, Burkhard Buchheim, Alexander Dilje, Hans-Jürgen Friedrich, Helmut Hauck, Holger Kristandt, Alfred Radina, Jonas Schierling

Publication number: 20110299800Abstract: A bearing assembly comprises at least one bearing element abutting against at least one adjacent part at a contact surface. The bearing assembly can be manufactured by disposing a reactive nano-crystalline layer between the bearing element and the adjacent part in the area of the contact surface and then initiating an exothermic reaction in the reactive nano-crystalline layer, so that the bearing element bonds to the adjacent part in a materially-connected manner. The exothermic reaction involves at least partially heating the surface area of the bearing element and/or of the adjacent part that is located in the area of the contact surface.Type: ApplicationFiled: November 20, 2009Publication date: December 8, 2011Inventors: Stefanie Seufert, Helmut Hauck, Alexander Dilje, Hans-Jürgen Friedrich, Berthold Beyfuss, Alfred Radina, Jonas Schierling
