摘要： An axial seal assembly includes an inner annular shield having an axial portion disposable about the shaft at a position adjacent to the bearing and a radial portion extending radially outwardly from the axial portion. An outer annular seal has an axial portion engageable with the outer member bore, a radial portion extending radially inwardly from the axial portion and on or more axial sealing lips engaged with the shield radial portion. The seal radial portion is spaced from the shield radial portion by a predetermined axial distance during use. The seal has at least one coupler section engageable with the shield radial portion or the shield axial portion when an axial spacing distance between the seal radial portion and the shield radial portion is less than the predetermined distance to retain the shield coupled with the seal when the seal assembly is separate from an outer member bore.

摘要： A wheel bearing apparatus includes a hub shaft having a flange to which a wheel is attached and which is located on a vehicular outer side, an outer ring, a plurality of rolling elements, an annular seal member, and an annular slinger. The slinger has a circular ring portion that is in contact with the flange and a tube portion extending from the circular ring portion toward a vehicular inner side. The tube portion has pawl portions located on the vehicular inner side to engage with a recessed portion of an outer periphery of the hub shaft to inhibit the slinger from being displaced toward the vehicular inner side. The tube portion is further provided with a plurality of slits that is formed along a circumferential direction and that is open on the vehicular inner side. The slits include slits with different depths.

摘要： A universal joint includes a trunnion including an annular recess in an outer surface. A bearing cup is disposed on the trunnion and includes an inner diameter surface having a retention recess therein. A needle bearing assembly is disposed between an outer surface of the trunnion and the inner diameter surface of the bearing cup. A seal assembly is disposed at an open end of the bearing cup and includes a seal support insert including a radially outwardly protruding retention member engaged with the retention recess of the bearing cup. An elastomeric seal is molded to the seal support insert and includes a plurality of radially inwardly extending seal lips engaging the outer surface of the trunnion and a dust lip extending axially from the seal support insert and including a dust lip retention feature received in an annular recess of the trunnion.

摘要： 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.

摘要： A wheel bearing apparatus has an outer member, an inner member, at least one inner ring fit onto the inner member. Double row rolling elements are rollably arranged between the outer and inner raceway surfaces, via cages. A seal is mounted on one end of the outer member. The seal has side lips adapted to be in sliding contact with the wheel hub. The seal has three inclined side lips each extending radially outward from the seal body. The lips are adapted to be in sliding contact with the base of the wheel mounting flange. Interference of the side lips against the base of the wheel mounting flange is set so that the radially inner side lip has a smaller interference than that of the radially outer side lips, in order.

摘要： A hub-bearing unit for rotatably is provided with a stationary radially outer ring, a radially inner ring, an annular gasket, and a second metal insert. The radially inner ring includes a flange for mounting a wheel and a sealing device having a first metal insert, annular shaped, steadily fixed at an end portion of the outer ring facing the flange. The annular gasket includes a plurality of elastomeric sealing lips and steadily fixed to the metal insert. The second metal insert is steadily fixed on an axial cylindrical surface of the inner ring. The gasket presents a first axial contacting lip. The first axial contacting lip slidingly contacts a substantially frustoconical portion of the metal insert.
