An article movement system includes an article and at least one ball wheel. The article has first and second article surfaces meeting at a first article edge. The ball wheel is located along the first article edge and includes a ball, a bearing arrangement and a shell. The ball engages a surface underlying the article, the bearing arrangement supports the ball for omni-directional rotational movement, and the shell is located along the first article edge and contains the ball and the bearing arrangement. The shell defines a non-circular ball opening through which a portion of the ball extends to contact the underlying surface. The article, the bearing arrangement and the shell are configured such that the ball wheel is able to support the article for omni-directional rolling motion over the underlying surface with either of the first and article surfaces parallel thereto, and at any orientation therebetween.

An all-terrain load transport system including a cylindrical first base member and at least three pairs of arms is provided. A handle is removably attached to an attachment member disposed on the cylindrical first base member. The cylindrical first base member defines a space for receiving at least one piece of accessory equipment. Each pair of the three pairs of arms defines a wheel support assembly at an end of each pair distal from an outer periphery of the cylindrical first base member. The three pairs of arms are detachably attached to the outer periphery of the cylindrical first base member. The wheel support assembly includes a cylindrical second base member defining a space for receiving a spherical wheel. The spherical wheel moves omnidirectionally within the defined space. Roller bearings positioned along an inner periphery of the cylindrical second base member facilitate the omnidirectional movement of the spherical wheel.

A wheel hub assembly assembly having a central axis (X) and covers therefore. An outer ring provided with a tubular mounting portion, and a cover having a keying portion which is inserted inside the tubular mounting portion. The cover is made of plastic material, the keying portion comprises an annular seat made of plastic and a sealing element made of rubbery elastic material. The sealing element is defined by a solid of rotation mounted inside the annular seat over a whole of an axial length of the annular seat so as to project radially outside of the annular seat to make contact with the tubular mounting portion of the outer ring thereby sealingly closing the wheel hub assembly.

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 nipple for spoked wheels of the tubeless type comprises a first and a second shoulder which are formed on a rod with a blind axial hole which is internally threaded at an end of the rod which is distal from the opening of the axial hole and in a zone of the rod which is proximal with respect to the opening, respectively. A first recess for a sealing ring is formed on the rod behind the first shoulder and at least a second recess for a second sealing ring is formed on the rod between the first recess and the second shoulder.

There is provided a wheel bearing sealing arrangement for a wheel bearing of a vehicle, comprising an outboard bearing having an outboard periphery intended to face away from a central longitudinal axis of the vehicle and an inboard periphery intended to face towards the central longitudinal axis of the vehicle, wherein the outboard bearing comprises a first race-forming part and a second race-forming part which surrounds the first race-forming part; an outboard seal arranged between the first race-forming part and an opposite part; and a safety washer pressed against the outboard periphery of the first race-forming part, wherein the outboard seal comprises a sealing part pressed against and in direct contact with the safety washer. There is also provided a vehicle comprising such a wheel bearing sealing arrangement.

A hubcap for a heavy-duty duty vehicle that includes mounting structure that is formed with and cooperates with a side wall of the hubcap to provide a stiff, rigid structure that enables non-cantilevered connection to a wheel hub. The mounting structure can be a plurality of elongated bosses circumferentially spaced about the side wall that are formed with corresponding elongated bolt openings to enable the non-cantilevered attachment to the wheel hub. The elongated bosses cooperate with the hubcap side wall to provide a stiffened or rigid structure between the elongated bolt openings for increased and more uniform clamping force on a sealing gasket between the hubcap and the wheel hub. The hubcap profile provides clearance for removal of an outboard mounted disc brake rotor in heavy-duty vehicle wheel end assemblies that include such rotor configurations. The hubcap may support simple mounting of a hub odometer.

An all-terrain load transport system including a cylindrical first base member and at least three pairs of arms is provided. A handle is removably attached to an attachment member disposed on the cylindrical first base member. The cylindrical first base member defines a space for receiving at least one piece of accessory equipment. Each pair of the three pairs of arms defines a wheel support assembly at an end of each pair distal from an outer periphery of the cylindrical first base member. The three pairs of arms are detachably attached to the outer periphery of the cylindrical first base member. The wheel support assembly includes a cylindrical second base member defining a space for receiving a spherical wheel. The spherical wheel moves omnidirectionally within the defined space. Roller bearings positioned along an inner periphery of the cylindrical second base member facilitate the omnidirectional movement of the spherical wheel.

A wheel bearing assembly includes a fixed inner axle with at least one inner race, a rotatable outer hub disposed about the axle and having at least one outer race and rolling elements disposed between the inner and outer races. An annular seal is disposed between the axle and the hub and is located adjacent to the inner and outer races. A shield is spaced axially from the seal such that the seal is disposed between the rolling elements and the shield. The shield includes a rigid annular body having an outer radial end coupled with the outer hub, preferably by a plurality of couplers, and an inner radial end defining a central opening for receiving the axle and located adjacent to the inner axle or a component disposed upon the axle. As such, the annular body substantially obstructs an annular interior space to prevent substances from contacting the seal.
