A bearing unit having a radially outer ring provided with at least one raceway, a radially inner ring provided with at least one raceway, at least one row of rolling elements interposed between the radially outer ring and the radially inner ring, at least one containment cage for keeping the rolling elements of the rolling element row in position, and a seal interposed between the radially inner ring and the radially outer ring. An anchoring element mechanically locks the seal in a first seat of the radially inner ring, and the anchoring element is housed in a second seat of the radially outer ring.

A bearing unit including a radially outer ring, a radially inner ring, a row of rolling bodies interposed between the radially outer ring and the radially inner ring, a containment cage for keeping the rolling bodies in position defined by a plurality of arched bridges and a plurality of flattened connecting elements interposed between the bridges, a sealing screen interposed between the radially inner ring and the radially outer ring made of composite material provided with an annular central portion having a toroidal surface, a radially inner lug, and a radially outer deflector projecting towards the cage, and a channel between the cage and the sealing screen, axially defined by the lug, the toroidal surface, and the deflector.

A bearing seal includes at least one first metal-plate element having an attachment region for attaching the first metal-plate element to a bearing inner ring, at least one seal element attached to the first metal-plate element, and at least one spring element configured to press at least one region of the seal element in a radially outward direction. Also a wheel bearing assembly including the bearing seal.

A seal assembly for a truck wheel hub assembly includes an inner annular case having an axial portion disposable about an axle and a radial portion extending radially outwardly from the axial portion. An outer annular case is coupleable with a hub bore and has a radial portion extending radially inwardly from the bore. An annular elastomeric seal member has a base portion disposed on the outer case and at least one flexible axial seal lip with a first end integrally formed with the base portion and a second, free end sealingly engageable with the radial portion of the inner case. A radial projection extends radially inwardly from the outer case radial portion and has an inner radial end located adjacent to and spaced radially outwardly from the inner case axial portion or an outer circumferential surface disposed about the axle so as to form a labyrinth seal gap.

A wheel bearing assembly with an outer race, a first roller bearing, a second roller bearing, a first shield, and a second shield. The outer race may have a first inner surface and a second inner surface. The first roller bearing and the second roller bearing may have a plurality of rollers configured to engage with the first inner surface and with the second inner surface, respectively. The first shield and the second shield may be configured to engage with the first roller bearing and the second roller bearing, respectively, and push the first roller bearing and the second roller bearing against the first inner surface and the second inner surface, respectively. The first shield and the second shield may each have a rubber seal configured to reduce passage of fluid into or out of the first roller bearing and the second roller bearing, respectively.

A seal assembly is for a wheel hub assembly and includes an inner annular case disposable about an axle and having a radial portion extending radially outwardly from the axle. An outer annular case is coupleable with a hub bore and has a radial portion extending radially inwardly from the bore. An annular elastomeric seal member has a base portion disposed on the outer case and at least one flexible axial seal lip with a first end integrally formed with the base portion and a second, free end sealingly engageable with the radial portion of the inner case. The lip extends generally axially and radially outwardly from the first end to the second end such that the lip is biased radially outwardly by centrifugal force during rotation of the hub to reduce sealing pressure of the lip second end on the inner case radial portion.

Disclosed herein is a threaded bottom bracket comprising: an internal sleeve, a ball bearing, wherein an inner race of the ball bearing is an extended inner race, a cup fit to concentrically hold the ball bearing, wherein the cup is coupled to the internal sleeve, a labyrinth, the labyrinth coupled to the ball bearing and fit to prevent water and debris from entering the ball bearing, wherein the labyrinth and the cup form a path, and a rotary seal disposed between the ball bearing and the labyrinth, the rotary seal having an external seal that seals against the extended inner race.

A rolling bearing 1 includes an outer ring 1A, an inner ring 1B, and a plurality of rolling elements. The outer ring IA includes a first outer ring 10 and a second outer ring 20.
