A seal arrangement for a wheel bearing having first bearing part and a second bearing part integrally connected to a wheel bearing flange, between which bearing parts rolling elements are guided. The sealing arrangement includes: a carrier element, which is connected to the first bearing part and an elastic element is provided on the carrier element. The elastic element has at least one sealing lip, and the carrier element has a fastening section, which is connected to the first bearing part. A stop part is fastened to the second bearing part with which the at least one sealing lip is in rubbing contact. The wheel bearing flange has an axial projection at least partially surrounds an axial projection of the first bearing part, and an inner surface of the axial projection of the wheel bearing flange forms a seat for the stop part.

A vehicle wheel bearing includes a wheel hub having a hub flange to which a wheel is mounted; at least one inner ring mounted to one side of the wheel hub in a press-fitting manner; an outer ring provided radially outward of the inner ring and having a mounting flange to be mounted to the vehicle body on an outer circumferential surface; one or more rolling elements provided radially inward of the outer ring; and a sealing member configured to prevent foreign matters from flowing into the wheel bearing. The sealing member includes a first sealing member mounted to the wheel hub or the inner ring; and a second sealing member mounted to the outer ring. One or more elastic sealing lips are provided in one or both of the first sealing member and the second sealing member.

A wheel hub bearing for motor vehicles including a rotatable hub provided with a flange for the engagement of the hub to a wheel of a vehicle and provided with a radially outer free portion and a bearing unit provided with a radially outer ring for the engagement of the wheel hub bearing to a knuckle of the vehicle and a radially inner rotatable ring angularly connected to the hub. Furthermore, the wheel hub bearing has a device for detecting a vehicle parameter and provided with an encoder and a sensor in communication with the encoder. The encoder is ridgidly coupled to the radially outer free portion of the flange to jointly rotate with the hub.

A wheel bearing device (1) provided with an outer sealing member (7) in which: a core metal (8) having formed therein multiple seal lips is fitted to the outer opening of an outer ring (2); a metal ring (9) is fitted to the outer peripheral section of a hub ring (3) so as to oppose the core metal. The multiple seal lips are brought into contact with the metal ring, so that a portion between the outer ring and the hub ring is sealed. An annular outer member side weir part (11f) that protrudes to the outer side, in a radial direction, as compared to the outer edge of the metal ring so as to surround the metal ring is provided to the core metal, and an outer member side expanded-diameter part (8g) that holds grease is formed in the inner peripheral surface of the outer member side weir part.

A structural unit for assembly to a trunnion of a universal joint bearing providing a cup, a sealing ring, which is fixed to the cup, and a shield, which is connected to the cup in a state in which the structural unit is not assembled to the trunnion. The cup includes a bottom and the sealing ring provides at least one sealing lip that points in a direction with an axial component towards the bottom.

A bearing assembly includes a bearing flange and a flange receptacle having a longitudinal axis, which comprise a mutual axial stop and a fixing for securing the mutual stop position. The fixing is designed as a wedge-type clamp which can be actuated transversely, in particular radially, to the longitudinal axis. The wedge-type clamp clamps the bearing flange and the flange receptacle axially into the mutual stop position. The bearing assembly may be, for example, provided for a robot and its rotary body.

A sealing device adapted to be disposed between an inner member and an outer member that rotate relative to each other includes a first sealing member including a cylindrical part adapted to be mounted to the outer member, and an annular part that extends radially inward from the cylindrical part; and a second sealing member including a sleeve adapted to be mounted to the inner member, and a flange. The first sealing member includes a lip that extends toward the flange of the second sealing member. An annular first clearance is provided between the flange and the cylindrical part of the first sealing member. The second sealing member includes a labyrinth lip extending from the flange radially outward and extending toward the atmosphere side more than the cylindrical part of the first sealing member, and a second clearance is provided between the labyrinth lip and the outer member.

A wheel hub bearing for motor vehicles including a rotatable hub provided with a flange for the engagement of the hub to a wheel of a vehicle and provided with a radially outer free portion and a bearing unit provided with a radially outer ring for the engagement of the wheel hub bearing to a knuckle of the vehicle and a radially inner rotatable ring angularly connected to the hub. Furthermore, the wheel hub bearing has a device for detecting a vehicle parameter and provided with an encoder and a sensor in communication with the encoder. The encoder is ridgidly coupled to the radially outer free portion of the flange to jointly rotate with the hub.

A sealing device adapted to be disposed between an inner member and an outer member that rotate relative to each other includes a first sealing member including a cylindrical part adapted to be mounted to the outer member, and an annular part that extends radially inward from the cylindrical part; and a second sealing member including a sleeve adapted to be mounted to the inner member, and a flange. The first sealing member includes a lip that extends toward the flange of the second sealing member. An annular first clearance is provided between the flange and the cylindrical part of the first sealing member. The second sealing member includes a labyrinth lip extending from the flange radially outward and extending toward the atmosphere side more than the cylindrical part of the first sealing member, and a second clearance is provided between the labyrinth lip and the outer member.

A wheel hub assembly includes a mounting base and a wheel hub supported for rotation on the mounting base by a plurality of bearings disposed within an annular space between the hub and base. A sealing system is provided that seals all points of intrusion into the space such that liquid contaminants are inhibited or precluded from entering the space and reaching the bearings when the assembly is subjected to an immersion/thermal shock test in which the assembly is heated to an elevated temperature and then immersed on a cold bath of the liquid contaminant. A method of testing the sealing integrity of wheel hub assemblies is also provided
