A sealing device for a hub/wheel assembly with a roller bearing. The sealing device includes a guard, made of plastic. The guard is coupled to an outer ring of the bearing to seal off the bearing. The guard has a cylindrical mounting wall with an outer lateral surface coupled to an inner lateral surface of a collar of the outer ring, and a snap-engagement step for engaging with the collar made along the outer lateral surface so that it snap-fits in a contoured annular groove made along the collar about the axis. An annular gasket is made of elastomer and co-injection-molded inside an annular groove made in the cylindrical mounting wall on the same side as the snap-engagement step.

Wheel bearing assembly for motor vehicles, the assembly being provided with a wheel hub and a bearing unit in turn provided with a radially outer ring and at least one radially inner ring provided, respectively, with a first raceway and at least one second raceway, with at least one row of rolling bodies arranged between the radially outer ring and the at least one radially inner ring, and with a cage for containing the at least one row of rolling bodies; the wheel bearing assembly is moreover provided with sealing means integrated in the cage and provided with at least two radial contact lips made of elastomeric material, with at least one first radial lip in contact with the radially inner ring and with at least one second radial lip in contact with the radially outer ring.

A UTV double row tapered wheel bearing assembly may include a first inner diameter race, a second inner diameter race axially offset from the first inner diameter race, and an outer diameter race radially offset from the first inner diameter race and the second inner diameter race, the outer diameter race formed as a single integral member. A first ring of rollers may be disposed between the outer diameter race and the first inner diameter race. A second ring of rollers may be disposed between the outer diameter race and the second inner diameter race. A first shield may be coupled to a first axial face of the bearing, and a second shield may be coupled to the second axial face of the bearing.

A hub for a bicycle includes a hub shell and an axle device. The hub shell is supported rotatably relative to the axle device by way of bearing devices. A bearing device is configured as a roller bearing, and includes two bearing rings with rolling members disposed between, and is sealed axially outwardly. Between the bearing rings, the roller bearing includes a modular unit, at which a sealing unit is configured for laterally sealing the roller bearing, and including guide units protruding laterally inwardly from the modular unit for guiding the rolling members.

A sealing structure includes a seal member and a slinger. The seal member includes a gutter positioned between a seal fixing portion and a seal lip in an axial direction. The gutter and the seal lip are positioned at different positions in the axial direction, and a first axially extending portion radially faces a whole of the seal lip and a part of the gutter on one axial side. A communication portion communicating with an outside of the sealing structure is formed between the seal fixing portion and the first axially extending portion. The communication portion radially faces a part of the gutter on the other axial side.

Sealing device for a wheel hub assembly provided with a rolling bearing, the sealing device being provided with a shield mounted on an outer ring of the bearing and with an annular cylindrical wall having an inner lateral surface mounted on an outer lateral surface of a collar of the outer ring; and with a sealing material fixed to the shield; an annular snap catch being positioned radially inside the cylindrical wall and extending radially from the inner lateral surface through a specified radial thickness so as to be snap-fitted into a circular groove formed on the outer lateral surface of the collar, and the sealing material being positioned behind the catch before the shield is mounted on the outer ring, with a radial overall dimension smaller than the thickness of the catch.

A wheel end assembly having a steering knuckle, a hub, and a compression ring. The steering knuckle may have an opening that may extend around a spindle. The hub may be rotatably disposed on the spindle. The compression ring may be disposed on the hub and may be at least partially disposed in the opening.

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.

The wheel bearing device includes a hub shaft including a flange portion on one axial side of the hub shaft, an outer ring, a plurality of rolling elements, a cage, and a seal member attached to an end portion of the outer ring on the one axial side. A side surface of the flange portion on another axial side of the hub shaft includes a first side surface having first roughness and a second side surface having second roughness larger than the first roughness. The seal member includes a lip provided facing the second side surface, and a distal end of the lip includes a worn surface that is worn by being in sliding contact with the second side surface.

A packaging system having an outboard guard and an outboard retainer cap. The outboard guard includes an outboard guard opening having a hole through the planform of the outboard guard, an engagement portion having an annular surface radially surrounding the outboard guard opening, an outboard bearing protector portion having an annular surface radially surrounding the engagement portion of the outboard guard, and an outer rim having an annular surface radially surrounding the outboard bearing protector portion. The outboard retainer cap is configured to be removably affixed to the outboard guard and includes an outboard alignment protrusion having a circular surface, an engagement portion having an annular surface radially surrounding the outboard alignment protrusion, and a retaining flange having an annular surface radially surrounding the engagement portion of the outboard retainer cap.
