A seal assembly is disclosed. A seal assembly may comprise a seal carrier, a compliant structure comprising a first end and a second end, wherein the first end is coupled to the seal carrier, and/or a support structure coupled to the second end. The seal carrier may be integral with the compliant structure.

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.

A rolling-element bearing assembly includes first and second bearing rings that form a bearing interior between them and a plurality of rolling elements disposed in the bearing interior and a seal assembly for sealing the bearing interior. The seal assembly includes a seal carrier and a seal element having at least one primary seal lip for sealing the bearing interior and a secondary seal lip for sealing against external contamination. The seal element is connected to the seal carrier such that the primary seal lip and the secondary seal lip abut axially against an axial end surface of the second bearing ring.

Disclosed is a bearing assembly, in particular a large bearing assembly, including at least one inner ring and at least one outer ring, between which at least one circumferential seal is disposed that slips on a circumferential slip surface of the inner ring or of the outer ring, wherein guide channels are formed on the slip surface or the circumferential seal.

A bearing provides a first ring and a second ring capable of rotating concentrically relative to one another, and at least one seal provided with at least one sealing lip. The bearing further includes a sealing module providing a carrier reversibly secured to the first ring, the seal being mounted radially into contact with the carrier, a friction ring reversibly secured to the second ring, the sealing lip of the seal coming into contact with the friction ring, and at least one spacing element axially interposed between the friction ring and the second ring.

A rolling bearing providing a first ring and a second ring capable of rotating concentrically relative to one another, at least one row of rolling elements arranged between first and second raceways of the first and second rings, and at least one seal provided with at least one sealing lip. The first ring includes at least one first rolling ring having the first raceway and a first sealing ring secured to the first rolling ring. The second ring further includes at least one second rolling ring having the second raceway and a second sealing ring secured to the second rolling ring. The bearing also further includes a sealing module reversibly secured to the first and second sealing rings.

A sealing assembly for a rolling-element bearing includes a first seal element and a second seal element, the first seal element including a first support member mounted on a first bearing ring, a first seal body extending radially from the first support member and having an oblique side surface, and at least one first seal lip extending radially from the first seal body to the second ring to form a first seal and the second seal element including a second support portion mounted on the second ring, a second seal body projecting from the second support portion and at least one second seal lip extending from the second seal body to the oblique side surface to form a second seal. A buffer member extends from the first seal element toward the second seal element and has first and second radially spaced annular ribs that extend toward the second seal element.

A support assembly for moving shafts, comprising a bearing unit positioned in a casing, and a cover for fluid sealing the casing. The support assembly comprises double level of protection provided by two distinct sealing devices that keep the bearing unit protected from washing liquid even in the most demanding conditions of use. The better sealing configuration aids in overall better sealing of the bearing unit; greater resistance to contaminants; and improving the sealing performance of the whole support assembly.

In an outer ring rotating rolling bearing (10), an inclined surface is formed on an outer peripheral surface of an inner ring (12) and decreasing in diameter toward an axially outer side, a seal member (20) includes an annular core metal (21) and an annular elastic member (22) fixed to the core metal (21), and an elastic member (22) includes a neck portion (28) extending from an inner peripheral edge portion (24a) of the core metal (21) toward a radially inner side and a seal lip (30) formed at a tip end portion of a neck portion (28) and brought into contact with the inclined surface (41) of the inner ring (12) with a tightening margin. Here, T2≥T1, where a width of the core metal (21) is T1 and a thickness of the neck portion (28) is T2. As a result, even in an environment where the outer ring is rotated at high speed and the seal member is subjected to external pressure (pressure fluctuation), the influence of centrifugal force generated on the seal lip can be suppressed, and the sealing performance of the seal member can be ensured.

A sealing assembly for a rolling-element bearing includes a first seal element and a second seal element, the first seal element including a first support member mounted on a first bearing ring, a first seal body extending radially from the first support member and having an oblique side surface, and at least one first seal lip extending radially from the first seal body to the second ring to form a first seal and the second seal element including a second support portion mounted on the second ring, a second seal body projecting from the second support portion and at least one second seal lip extending from the second seal body to the oblique side surface to form a second seal. A buffer member extends from the first seal element toward the second seal element and has first and second radially spaced annular ribs that extend toward the second seal element.
