摘要:
The cam follower roller device providing a tappet body extending along an axis, an insert mounted in the tappet body, a pin mounted at least on the insert and a roller mounted on the pin. The device further provides a retaining washer mounted into a bore of the tappet body so as to axially retain the insert inside the tappet body. The tappet body provides retention means, cooperating with the washer to axially retain the washer relative to the tappet body. The retaining washer is axially interposed between the insert and the retention means.

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.
摘要:
A cage for a rolling bearing, wherein the cage is intended to ensure the circumferential spacing of a row of rolling elements. The cage comprises pockets for the rolling elements and connecting portions, each connecting portion connecting two successive pockets. At least one of the connecting portions is elastically deformable at least in a circumferential direction so as to allow the two associated pockets to move relative to one another in the circumferential direction.

Rolling bearing cage (5) for an electric steering system of a motor vehicle, designed to ensure the circumferential spacing of the balls (4), comprising a plurality of first sockets (8) provided with means (8a) for axially retaining the cage (5) on a ball (4) and a plurality of second sockets (9) without means for axially retaining the cage (5) on a ball (4).Each of the first sockets (8), with a ball (4) housed in the first corresponding socket (8), has a first axial clearance, a first radial clearance and a first circumferential clearance (J1c) and each of the second sockets (9), with a ball (4) housed in the second corresponding socket (9), has a second axial clearance, a second radial clearance and a second circumferential clearance (J2c).
摘要:
A seal is for a rolling bearing including inner and outer rings relatively rotatable about an axis. The seal includes a generally annular body having a radial portion with inner and outer ends. A static sealing portion at least partially surrounds one of the inner and outer ends of the body radial portion and is configured to form a static seal with a proximal one of the bearing inner and outer rings. A dynamic sealing rim extends generally axially from the other one of the inner and outer ends of the body radial portion, the rim being configured to form a dynamic seal with the other one of the bearing inner and outer rings and being spaced radially from the other one of the inner and outer rings so as to define an annular space for receiving a lubricant.

This rolling bearing comprises an outer ring (4), an inner ring (6), rolling bodies (10) arranged between the outer ring and the inner ring, one a sealing gasket (20) mounted on a first ring (4) and extending towards the second ring (6), to the extent that a sealing edge (26) of said sealing gasket is in sliding contact with the second ring. An annular shield (50) is mounted on the second ring (62) and extends radially towards the first ring (4). This shield (50) is provided with at least one annular lip (58) in sliding contact with a lateral face (28) of the sealing gasket (20).
