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.

A bicycle component includes a hub shell for a wheel of an at least partially muscle-powered bicycle, wherein the hub shell is rotatably supported by at least one bearing device. An adapter unit is disposed on one end of the hub shell. The adapter unit includes an inner stopper having an inner stop face for transferring a clamping force to the bearing device and an outer stopper with an outer stop face transmitting at least part of the clamping force. The adapter unit includes a first and a second stopper component transmitting the clamping force.

A wheel bearing arrangement having a rotational axis, having at least an outer ring; an inner ring which can be rotated about the rotational axis relative to the outer ring; and a bearing seal arrangement which comprises a running ring which is configured as an outer seal and a seal body which is configured as a main seal, wherein the running ring is supported on the inner ring and the seal body is supported on the outer ring, wherein the running ring is of C-shaped configuration in cross section with a radial and axial extent with a side which is open towards the rolling bodies.

A noncorrosive, water-impermeable gasket is used between a wheel rim and a hub assembly so that they do not corrode together making their separation difficult or impossible. The gasket includes a gasket flange with a gasket bolt pattern that is alignable with a hub bolt pattern of the hub assembly and a rim bolt pattern of the wheel rim.

A bearing device for vehicle wheel includes a sealing ring (71) that includes: a core bar (72) and sealing rubber (73). The sealing rubber (73) includes: a first sealing lip (73b) that is formed to the radial-direction outside of the fitting part (72a) and has a tip end part that is in sliding contact with a sealing plane part (3h); and a second sealing lip (73c) that is formed to the radial-direction inside of the fitting part (72a) and has a tip end part that is in sliding contact with the sealing plane part (3h). A flat surface (73e) that can be contacted by a press-fitting tool (P) and by the tip end part of the fitting part (72a) of another bearing device for vehicle wheel is formed between the first sealing lip (73b) and the second sealing lip (73c).

A seal assembly device is configured to attach an annular seal by press-fitting to an axial end portion of a first raceway member of a wheel bearing device. The seal assembly device includes: a columnar guide member including a contact surface configured to contact a plurality of rolling elements provided along a raceway surface formed on the first raceway member from a side opposite to the raceway surface, the contact surface being continuous in a circumferential direction; a pressing member configured to move in an axial direction along the guide member toward the axial end portion so as to press the seal in the axial direction and to press-fit the seal into the axial end portion; and a reference member configured to restrict a movement stroke of the pressing member with respect to the guide member in the axial direction.

A drive wheel end includes a hub assembly, an axle, an axle shaft passing through an interior of the axle and rigidly coupled to the hub assembly outside the interior, a bearing system including (i) at least one bearing between the hub assembly and the axle and (ii) a bearing seal between the at least one bearing and an air side of the bearing system, and a filter spanning gap between the axle and at least one of the hub assembly and the axle shaft externally to the axle, to filter flow between the bearing system and the interior. The filter may include a frame and a flexible lip. The frame forms a central aperture and at least one opening radially outwards from the central aperture, and includes a size-discriminating material covering each opening. The flexible lip extends radially inwards from the frame.

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.

A sealing device for a bearing unit having an axis of rotation and providing; a static component placed on a non-rotatable outer ring having a reinforcement support that abuts the outer ring and elastomeric material disposed on the reinforcement support, the elastomeric material forming first and second lips; a rigid shield configured for placement on one of a rotatable hub and a rotatable inner ring; the first and second lips have an equilibrium position where they do not contact the metallic shield; the elastomeric material forming a third lip that contacts the rigid shield to form an internal volume of the sealing device, the second lip and the rigid shield define a labyrinth seal in communication with the internal volume; the second lip, does not extend a full three hundred sixty degrees around the axis of rotation. This creates a channel for drainage of contaminants from the internal volume.

A unitized wheelend is provided. The unitized wheelend includes a hub having an inboard side bounded by an oil seal and an outboard side bounded by a retainer releasably coupled to the hub. The unitized wheelend assembly includes an inboard bearing assembly, a spacer, an outboard bearing assembly, and a spindle nut assembly.
