Abstract: A clutch thrust bearing device includes a rolling bearing having a fixed ring, a rotatable ring, and a plurality of rolling elements between the rings; an axially movable piston disposed between a housing and the rolling bearing and having a radial plate pressing against an axial contact surface of the fixed ring; at least one resilient seal member sealing the piston relative to the housing; and a resilient body exerting an axial preload onto an axial contact surface of the rotatable ring. The rolling bearing is axially movable by the piston to compress the resilient body. A resilient sleeve is mounted to the fixed ring and has at least one sealing lip in sliding contact with the rotatable ring.

Abstract: A cam follower roller device having a tappet extending along a longitudinal axis and including a cylindrical tappet body defining a bore. The device further having a rolling assembly arranged within the bore, and including a support body with a base and flanges, a pin and a roller. Each of the flanges of the support body is provided with an outwardly protruding portion that extends transversally from the flange towards the tappet body. The tappet body includes a support diametrically opposed and having each a transverse surface that cooperates with the protruding portion of the support body to longitudinally block the support body.

Abstract: A rotating bearing assembly having a stationary housing, a rotating shaft, and a rolling bearing radially arranged between the stationary housing and a shaft end of the rotating shaft. The rolling bearing provides a seal that includes a stiffening insert and a sealing gasket disposed between the inner ring and the outer ring on an axial side of rolling bearing. The rolling bearing is open on the opposite axial direction to the shaft end. A cage includes an annular heel oriented towards the axial side of the shaft end, two circumferentially adjacent pockets being separated by a projected portion that axially extends from the heel towards the open axial side of rolling bearing.

Abstract: A pulley device for a tensioner roller or winding roller for a transmission element, providing a bearing and a pulley. The pulley including two pulley elements that are C-shaped in axial section. At least one of the pulley elements has an axial through-opening, the other pulley element providing an axially protruding portion housed in the opening, a collar being formed by deformation of the protruding portion in order to provide axial retention with the opening. The at least one through-opening is provided at its periphery with at least one recessed zone formed in a substantially radially set-back manner with respect to the protrusion, which passes through the opening.
