  • Publication number: 20110255817
    Abstract: A roller bearing cage includes at least one bridge element having a surface provided for directly opposing an outer surface of a roller body. A plurality of ship-hull-shaped or droplet-t-shaped macroscopic recesses is formed in the surface for retaining a lubricant therein. The recesses have at least one of a width and a depth in the circumferential direction of the roller body that diminishes towards at least one end in the circumferential direction. A first group of the recess diminishes in a direction substantially towards one of the ends and a second group of the recess diminishes in a direction towards the other end.

  • Publication number: 20110222809
    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, which extends into the junction portion between the bearings in the assembled state of the bearing support and at least partially fills the junction portion.

  • Publication number: 20110222808
    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. The bearing support comprises at least first and second portions that are connected together. The first portion is formed as a component that has cylindrical openings configured to receive or seat the respective bearing outer rings and to surround the entire circumference of the respective bearing outer ring. The second portion is formed as a support plate. A bearing assembly includes the bearing support with a bearing seated in each of the respective cylindrical openings.

  • Publication number: 20110211782
    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: 20100329599
    Abstract: A roller bearing cage includes the following features: The cage comprises an annular circumferential element, from which bridge elements branch off, roller bodies of the roller bearing being disposable between the bridge elements, the circumferential element comprises a plurality of uniform section elements, and the initially-loose section elements and bridge elements are connected with each other to form the cage.

  • Publication number: 20100129022
    Abstract: A rolling bearing cage has at least U-shaped limited pockets for rolling bodies. In the rolling cage, the U-shaped delimitation of one of the pockets is configured by the bonded connection of two web elements on an annular circumferential element, the circumferential element is free of cavities and penetrations for a complete connection to sections of the web elements, and the elements are configured to have a shape adapted to each other for placing the elements in the intended position for the bonded connection such that the positions of the web elements on the circumferential element is predetermined in the circumferential direction and/or in the axial direction of the circumferential element.
