  • Publication number: 20160258487
    Abstract: A bearing assembly includes a roller bearing connected with a bearing support having a plate-shaped section. The bearing support has a receiving bore for an outer ring of the roller bearing, and the outer ring of the roller bearing is affixed to the bearing support with two affixing plates that are fixed to first and second end sides of the bearing support and that clamp the outer ring at two clamping surfaces. An axial spacing of the first and second end sides of the bearing support is smaller than an axial spacing of the clamping surfaces of the outer ring, and the two affixing plates have a different mechanical strength.

  • Publication number: 20140064652
    Abstract: A bearing support is configured to retain at least two bearings disposed closely adjacent to each other in a parallel relationship. Each bearing includes a bearing outer ring having a cylindrical outer circumferential surface. A support part includes a recess configured to hold the at least two bearings. At least one junction portion is defined in the support part adjacent portions of the cylindrical circumferential surfaces of the bearings that are not filled by the bearings when the bearings are inserted into the support part. The support part is connected with a cover part that axially abuts on the bearings. The cover part includes at least one support element that extends into the junction portion between the bearings in the assembled state of the bearing support and at least partially fills the junction portion.

  • Patent number: 8398311
    Abstract: 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.

  • Publication number: 20110299800
    Abstract: 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.
