The pulley device includes at least one annular protection shield, the shield retained axially in a first element from the pulley and coming into immediate proximity with the other element, the other element having at least one shoulder projecting radially ensuring that it is axially retained with the shield.

Pulley device

A pulley device for a tensioner roller or winding roller of a transmission element, providing a pulley, and a bearing. The bearing includes a rotating outer ring mounted to the pulley, a fixed inner ring, and at least one row of rolling elements arranged between the rings. The inner ring of the bearing has at least one end portion protruding axially with respect to the outer ring. The pulley is provided with at least one pulley element that is C-shaped in axial section. One of the at least one pulley elements is provided with a lateral portion extending substantially radially to pass into the immediate vicinity of an outer surface of the axially protruding end portion of the inner ring.

A pulley device comprising a pulley and a bearing. The pulley has at least one 'C-shaped' pulley part having an inner portion mounted on the bearing, an outer portion having an outer cylindrical surface dedicated to interact with a belt or a chain, and an intermediate portion extending substantially radially between axial ends of inner and outer portions on one axial side of pulley device. The outer cylindrical surface of outer ring is provided with at least one recess having in cross-section, a concave internal profile. The pulley part is provided with at least one protruding portion which inwardly extends beyond the inner cylindrical surface of inner portion. The protruding portion is received in a corresponding recess of outer ring so as to block the pulley part with respect to the outer ring in both axial directions.

Pulley device, in particular for tensioning idler or runner roller

A pulley device for a tensioner roller or winding roller of a transmission element, having a fixed inner element configured to receive a screw, a rotating outer element that is mounted to rotate coaxially about the fixed inner element and is intended to cooperate with the transmission element, and an annular protective flange bearing against a lateral surface of the fixed inner element. The fixed inner element provides a sleeve axially protruding from the lateral surface. The flange provides an inner axial portion mounted securely on an outer surface of the sleeve.

A pulley device configured to support a belt of a chain tensioning idler or runner roller includes a bearing having a rotatable outer ring and a coaxial fixed inner ring and a pulley having at least one C-shaped pulley part that has an inner portion with an inner surface mounted on an outer cylindrical surface of the bearing outer ring, an outer cylindrical portion having an outer cylindrical surface configured to contact the belt or the chain, and a radial intermediate portion between axial outer ends of the inner and outer cylindrical portions and an axial outer end of the outer cylindrical portion, wherein a ratio between a radial material thickness of the outer cylindrical portion and a radial material thickness of the inner cylindrical portion is strictly greater than 1.

A clutch release bearing for a motor vehicle includes a thrust element having an axial axis, a guide element supporting said thrust element, and a self-aligning sleeve including an annular body and a plurality of radial ribs extending towards the guide element from the body with a free end of each of the ribs radially contacting the guide element. The guide element includes angular retaining members for limiting angular movement of at least one radial rib of the plurality of radial ribs, which members may be integrally formed with the guide element or formed as separate elements attached to the guide element.

A Pulley device for a tensioning or winding roller for a transmission element including a pulley, and a rolling bearing provided with a rotating outer ring, the pulley being mounted on an outer surface of the outer ring, a fixed inner ring, the rings being coaxial and forming a radial space between them, and at least one row of rolling elements arranged in the radial space. The pulley device further includes at least one annular protection flange with a radial body. The flange is fixed to the rotating outer ring by crimping an axially protruding portion of the pulley towards an outer edge of the flange.

A combined electrical insulator and conductor assembly for a bearing disposable between a shaft and a housing. An annular insulator is disposeable about the bearing and configured to prevent electric current flow between an outer ring and the housing. An electrical conductor has retainer(s) releasably engaged with the insulator so as to couple the conductor with the bearing, an outer radial end and an inner radial end. The conductor outer radial end, or/and a portion of the conductor between the outer and inner ends, is conductively engageable with the housing and the conductor inner radial end is conductively engageable with the shaft so as to provide an electrically conductive path between the shaft and the housing. Preferably, the conductor includes a conductive disk having arcuate retainer clips engageable with an insulator groove of the insulator and a brush subassembly including conductive fibers engaged with the shaft outer surface.
