A sealing device for wheel hubs connected to constant-velocity joints including a first sealing assembly arranged between inner and outer rings of the wheel hub, and a second sealing assembly mounted on the inner ring and straddling the wheel hub and an outer ring of the constant-velocity joint. The first sealing assembly has a signal generating element having an annular insert mounted externally on a shield facing the constant-velocity joint and extending axially projecting above part of an annular step formed, on the same side as the constant-velocity joint, on a radially outer side surface of the inner ring, in a position immediately adjacent to the sleeve portion of the first shield. The second sealing assembly includes a tubular support keyed onto the inner ring by its first end on the outside edge folded in the manner of an L and shaped to engage inside the annular insert.

A sealing device for a wheel hub unit configured to form a static seal to protect the wheel hub unit from environmental contaminants. The sealing device including a shield that is coupled to a collar of the wheel hub unit. The sealing device having a cylindrical lateral mounting wall pressed into the collar, an annular seat with a blind end formed in the cylindrical lateral wall, and a sealing gasket positioned, inside the seat and compressed radially between the groove and the collar, and formed by a sealing compound to allow the formation of a bead against the cylindrical lateral wall in a transport and/or assembly configuration of the sealing device. The bead being movable into the seat by a scraping action exerted by the collar during the assembly of the shield.

A sealing device for a wheel hub unit configured to form a static seal to protect the wheel hub unit from environmental contaminants. The sealing device including a metal shield that is coupled to a collar of the wheel hub unit, and has an end wall, a cylindrical lateral wall integral with, and orthogonal to, the end wall. The lateral wall has twice the thickness of the end wall in order to impart stiffness to the metal shield, and a stop edge integral with the cylindrical lateral wall on the opposite side to the end wall, for bearing axially against the collar; a sealing gasket formed by a silicone-based sealing compound being provided to allow the formation of a bead against a cylindrical lateral wall in an assembly configuration of the sealing device.

An apparatus for a vehicle is provided that includes a spindle sleeve with a spindle sleeve inner surface axis. The spindle sleeve has a spindle sleeve outer surface axis that is not coaxial with the spindle sleeve inner surface axis. A hub with a hub axis coaxial with the spindle sleeve outer surface axis is also present. Also included are first and second bearings within the hub, and a containment seal that engages the hub and the spindle sleeve. A sleeve washer is included, and the containment seal is located between the first bearing and the sleeve washer in an axial direction of the hub.

An apparatus for a vehicle is provided that has an axle and a spindle sleeve with a spindle sleeve inner surface axis coaxial with the axis of the axle, and a spindle sleeve outer surface axis not coaxial with the axis of the axle. A hub has an axis coaxial with the spindle sleeve outer surface axis, and the hub at least partially defines a chamber. First and second ports extend through a wall of the hub to the chamber. The hub rotates about the spindle sleeve through the aid of two bearings. Lubricant is present within the chamber, and the first port provides a pathway for a pressurized fluid to be introduced into the chamber to force the lubricant out of the chamber via the second port.

A wheel bearing arrangement for a motor vehicle, including a wheel support and a wheel hub which is rotatably mounted on the wheel support by a wheel bearing in order to secure a wheel and to which a shaft is rotationally fixed, wherein a wheel bearing seal sealingly lies, on the one hand, against an inner ring of the wheel bearing, said inner ring sitting on the wheel hub, and, on the other hand, against an outer ring of the wheel bearing, said outer ring being secured to the wheel support. It is provided here that a wheel bearing pre-seal is rotationally fixed to the shaft adjacently to the wheel bearing and engages by a seal protrusion in a pre-seal receiving area formed in at least some sections between the outer ring and the wheel support.

An assembly for a tire inflation system including a spindle having a fluid conduit. The spindle is coupled with a rotary joint spindle, and the rotary joint spindle includes a fluid conduit in fluid communication with the spindle fluid conduit. A fluid collector ring is located about the rotary joint spindle such that the fluid collector ring may rotate. The fluid collector ring is also in fluid communication with the rotary joint spindle fluid conduit.

A bearing assembly configured to rotationally support a first component relative to a second component includes at least one bearing and at least one closure element configured to close an opening in the first component, which opening is disposed axially adjacent to the bearing. The closure element may be a cured body of foam that conforms to the shape of the opening or a ring mounted on the first component such that it covers the opening.

A wheel end assembly includes a spindle having a passage formed therein. The wheel end assembly also includes a hub cap assembly. The hub cap assembly has an inner housing and an outer housing. The inner housing and outer housing are in fluid communication via an air passage. An air spindle has an inboard portion and an outboard portion. The inboard portion is disposed in the spindle and the outboard portion is disposed in the inner housing. Also, the air spindle has a fluid passage. The fluid passage is in fluid communication with the passage formed in the spindle and the air passage formed in the hub cap assembly. A rotary air seal is disposed around the air spindle. A rotary oil seal is disposed around the air spindle and is spaced apart from the rotary air seal.

A hub for bicycles with a hub shell rotatably supported relative to a hub axle by roller bearings and a rotor rotatably supported relative to the hub axle by at least two rotor bearings and with a freewheel device with two interacting freewheel components namely, a hub-side freewheel component and a rotor-side freewheel component. The two freewheel components are movable relative to one another in the axial direction between a freewheel position and an intermeshing engaging position in which a driving torque can be transmitted. The hub-side freewheel component is compact in configuration and a hub bearing to rotatably support the hub shell is integrated and configured therein. An outer ring of the hub bearing is configured in an axial body section of the hub-side freewheel component. A sealing unit protects the interior of the hub bearing from the entry of dirt and water.
