  • Patent number: 9546682
    Abstract: A cage of a rolling bearing, the cage comprising: an annular heel centered on a central axis and having a constant radial thickness measured radially to the central axis; an axial portion extending from the heel substantially parallel to the central axis; and pockets delimited by the heel and the axial portion for receiving rolling elements. The axial portion has an axial length being greater than half the inner diameter of the pockets and an outside diameter being lesser than the outside diameter of the heel and which comprises between a first value equal to the pitch circle diameter of the cage minus half the radial thickness of the heel and a second value equal to the pitch circle diameter of the cage plus half the radial thickness of the heel. The pockets are spaced around the central axis having angular spacings being at least partly different from one another.

  • Patent number: 9103375
    Abstract: A cartridge bearing assembly for rotatably coupling a shaft with a housing includes a bearing having a central axis and opposing axial ends. The bearing includes first and second, axially spaced inner rings disposeable upon the shaft, at least one outer ring disposed circumferentially about the two inner rings, and first and second sets of rolling elements disposed between the inner and outer rings. A carrier includes a first tubular portion disposed generally about the bearing first axial end and a second tubular portion disposed generally about the bearing second axial end. The first and second tubular portions are coupled together to enclose the bearing, the carrier being at least partially disposeable within the housing bore so as to couple the bearing with the housing. Preferably, a coupler is provided to connect the first and second inner rings so as to establish preload within the bearing.

  • Patent number: 8226301
    Abstract: The suspension thrust bearing device, in particular for a motor vehicle, includes a rolling bearing forming an axial thrust bearing, a lower support cap of the rolling bearing that is provided with a body made of synthetic material, and a vibration-filtering element mounted on the body of the support cap. The filtering element includes at least one flange extending substantially radially and designed to form a flow deflector for reducing any ingress of water inside the rolling bearing.
