The end portion of the flange is curved and disposed axially facing the connecting portion. The curved end portion and connecting portion define an annular space that open radially towards the other ring. The curved end portion is mounted axially in contact against an outer lateral face of the seal.

Abstract: The bearing provides an inner race, an outer race and a wear race that is made of synthetic material and fastened to one of the races. The wear race is overmolded on at least one face of the race. The face includes at least one retention means that is covered with the synthetic material of the wear race and shaped to allow both the axial retention and the angular retention of the wear race relative to the race by shape complementarity with the wear race.

The device comprises a sleeve overmolded inside the bore of the inner ring and provided with a through-bore for mounting the fixing screw. The sleeve is provided with means of axially retaining the fixing screw inside the through-bore of the sleeve.

Abstract: The bearing provides an inner race, an outer race and a wear race that is made of synthetic material and fastened to one of the races.

Abstract: A bearing ring comprising at least one jamming bead of a seal, each bead protruding relative to a radial surface of the ring, in an orthoradial direction relative to a central axis of the ring.

Abstract: A bearing having an inner race, an outer race and a wear race mounted to press against an external face of one of the races and fastened on the race is provided. The wear race provides at least one annular flange locally covering an internal face of the race opposite the external face. The bearing further provides a sealing member fastened on the other race and includes at least one sealing lip in friction contact with the annular flange of the wear race.

Abstract: An engagement-disengagement, suspension or steering release bearing. The release bearing includes a rolling bearing forming a member for transmitting an axial force and comprising a rotating ring and a non-rotating ring between which a rolling chamber is mounted for rolling bodies and a sealing gasket, which is mounted on a first ring among the rotating and non-rotating rings, and which comprises a framework, having an edge folded down radially toward a groove arranged on a surface of the first ring, and a fitting, having a sealing lip in sliding bearing against, or adjacent to, a corresponding surface of the second ring, The fitting of the seal is suitable for filling the groove of the first ring and part of the fitting is jammed between the folded down edge of the framework and the groove in the configuration with the seal mounted on the first ring.

Abstract: The cam follower roller device provides a tappet body, a pin mounted into the tappet body, and a roller mounted on the pin and provided with an outer surface and with end faces, axially delimiting the outer surface. At least one lubricant supply through-hole is formed into the thickness of the tappet body and locally faces an edge of the roller delimited between the outer surface and one of the end faces.

Abstract: A rolling bearing including an inner ring, an outer ring, at least one row of rolling elements disposed between the inner ring and the outer ring, and (a) at least one seal fixed to one of the inner ring and the outer ring as well as (b) at least one internal sealing lip cooperating with a first portion of the other of the inner ring and the outer ring. The seal further includes at least one external sealing lip offset axially relative to the internal sealing lip on the exterior side of the bearing. The external sealing lip cooperates with a second portion of the other ring, wherein the second portion of the seal is separate from the first portion and situated axially facing the seal.

Abstract: A rolling bearing includes an inner race, an outer race, a row of rolling elements disposed between the inner and outer races, and a first seal fixed to one of the inner and outer races.
