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.

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.

Cartridge bearing assembly

The bump stop device, particularly for a motor vehicle, comprises a bearingforming an axial stop, a bottom support coverof the bearing and a bottom retainerfor a spring comprising at least one stiffening strut. The support coverand/or the retainercomprises at least one axial securing meansof the bottom retainer and of the bottom support cover, the said means being situated axially set back from a bottom end of the retainer.

Bump stop and associated MacPherson strut

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.

Suspension thrust bearing device and strut

The invention concerns a freewheel bearing device including an outer element and inner element arranged inside the outer element, and a free wheel provided with at least a wedging element, arranged between the inner element and the outer element to allow a free rotational movement in one direction between the outer element and the inner element and for transmission of a torque in the other direction between the outer element and the inner element, the free wheel including a ring provided with a cylindrical inner surface and a cylindrical outer surface, substantially aligned on a radial plane perpendicular to the axis of rotation of the device, and a torque limiting member adapted to limit the torque transmitted by the free wheel, the torque limiting member being arranged radially between said ring and the outer element or the inner element in contact with said ring and said element.

Freewheel bearing device with torque limiter

A suspension thrust bearing device includes a rolling bearing provided with two races and with rolling elements arranged between the races, and two caps each in contact with one race, one of the caps including a circular flange and the other cap including an axial portion provided with hooks intended for latching onto the said flange, which hooks leave an axial space of height b remaining between the said hooks and the said flange, one of the caps including an operational part provided with a chamfer intended to facilitate latching with the other cap, with an axial surface of height a and of diameter D and with a radial retention surface, and the other cap including an operational part provided with a chamfer intended to facilitate latching, with an axial surface of height c and with a radial retention surface, the sum of the heights a+b+c being greater than 1.9% of the diameter D.

Suspension thrust bearing device

A rolling bearing, in particular for motor vehicle steering column comprising an external ring (,) provided with a bearing raceway, an internal ring (,) provided with a bearing raceway, a row of rolling elements (,) arranged between the bearing raceways of said rings, tolerance ring (,) linking the internal ring with the shaft (,), and a spring washer (,) for blocking the bearing on the shaft (,). The external ring (,) comprises bosses (,) for axially maintaining the spring washer (,).
