A sealing device for a hub/wheel assembly with a roller bearing, the sealing device comprising a guard, made of plastic, which is coupled to an outer ring of the bearing so as to seal off the bearing, and which has a cylindrical mounting wall having an outer lateral surface coupled to an inner lateral surface of a collar of the outer ring. The sealing device includes a snap-engagement tooth for engaging with the collar made along the outer lateral surface so that the snap-engagement tooth snap-fits in a contoured annular groove made along the collar about the axis and an annular gasket made of thermoplastic elastomer being co-injection-molded inside a gripping seat made in the cylindrical mounting wall on the same side as the snap-engagement tooth, substantially at a corner defined between the cylindrical mounting wall and an annular reading wall transverse to the cylindrical mounting wall.

A rolling-element bearing includes an outer ring, an inner ring having a bore, a bearing interior between by the outer ring and the inner ring, a plurality of rolling elements in the bearing interior, and a cover attached to the rolling-element bearing such that it extends along an end face of the rolling-element bearing and covers the bearing interior, the inner ring, and the bore.

An end cover for enclosing and protecting a vehicle non-driven wheel hub assembly from a vehicle body inner side. The hub assembly includes an outer ring, an inner ring, and two rows of rolling bodies disposed therebetween. The outer and inner rings define an interior space of the hub assembly in a radial direction. An end of the outer ring facing the vehicle body inner side forms a spigot for connection purposes. The end cover is formed having a pressure fitting part tightly fitted to the spigot from a radial direction, and a radial main body part capable of closing the interior space of the hub assembly from an axial direction. The pressure fitting and the radial main body parts form an elastic retainer. The end cover is largely made of a plastic material, and an at least partially contained metal framework is formed in the elastic retaining region.

A method of manufacturing an annular insert molded article that suppresses contamination of a metal mold and generation of foreign matter without increase in material costs for an adhesive or contamination of a transfer jig, and has a high adhesion strength so that, when the annular insert molded article is attached to a rotating body, the adhesive does not peel off from the insert or remain as foreign matter in the rotating body. An annular insert molded article 1 is manufactured by injection molding in a state where a thermoset resin adhesive A is applied to a joining surface of an annular insert 2 attachable to a rotating body to an annular plastic 3 and then the annular insert 2 and the annular plastic 3 are placed in a metal mold.

A wheel hub assembly for motor vehicles, having a rotating hub and a bearing unit. The bearing unit including a radially outer ring provided with respective radially outer raceways, a radially inner ring provided with respective radially inner raceways, a plurality of rolling bodies positioned between the corresponding inner and outer raceways, a sensor for detecting the speed of rotation and the associated sensor holder. A cavity is formed in the radially outer ring of the bearing unit and a protuberance is formed on the outer mounting diameter of the sensor holder, the protuberance being able to be inserted inside the cavity to perform an anti-rotation retention function and ensure the mechanical orientation of the sensor holder.

A rolling bearing unit includes: an inner ring member having a recess on a first side in an axial direction along a rotation axis, which is recessed toward a second side in the axial direction; an outer ring member on an outer peripheral side of the inner ring member; a rolling body between the inner ring member and the outer ring member; a non-contact transmitter using electric field coupling capable of transmitting at least one of an electric power or a signal and including a stationary-side transmission part including a stationary-side electrode and a rotary-side transmission part including a rotary-side electrode facing the stationary-side electrode; and a covering member supported by the first side of the outer ring member in the axial direction, covering the first side of the inner ring member in the axial direction, and fixing the stationary-side transmission part to the first side in the axial direction.

A component assembly for a motor vehicle includes a housing and an actuating element that is rotatable about an axis. The assembly also includes an actuator which is configured to cause rotation of the actuating element. The assembly further includes a rotatable shaft which extends along a shaft axis and is disposed between the actuating element and the actuator and which is coupled to the actuating element and the actuator. The shaft is guided through a first through opening in the housing. A sealing system which seals a first end of the first through opening in relation to a second end, facing away from the first end, of the first through opening against liquid media passing through is provided in a radial direction that is perpendicular to the shaft axis so as to be between the shaft and a first internal wall of the first through opening. The sealing system has a first sealing element having a second through opening through which the shaft is guided. The first sealing element has a radially inward-pointing first internal side as well as a radially outward-pointing first external side. The first sealing element by way of the first internal side in a sealing manner encircles a shaft external side of the shaft. A first material of the first sealing element largely comprises polytetrafluoroethylene (PTFE).

A support assembly for movable, rotating or sliding shafts, having a bearing unit having an inner ring, an outer ring, and a row of rolling bodies interposed between the inner and outer rings, a casing, a cover for fluid sealing an opening of an internal seat of the casing, a rear sealing device on a side opposite the cover having a metal screen and a vulcanized rubber liner equipped with an axially outer first sealing lip and with an axially inner second sealing lip, an axially inner sealing device, having a first shield provided with a vulcanized rubber liner having a plurality of sealing lips, the outer ring having a step extending axially inward and provided with a second shield having a vulcanized rubber liner with a plurality of sealing lips.

A nut is used with being fixed to a sensor cap. The sensor cap is attached to an outer ring of a bearing in a wheel bearing device of an automobile. The sensor cap includes a sensor holder for holding a magnetic sensor. The nut is made of steel, and has a screw portion in which a bolt is screwed to attach the magnetic sensor to the sensor cap. A surface of the nut is coated with a zinc-nickel alloy plating layer with a nickel eutectic ratio of 8 to 18%.

A protective cover has an inner surface that is sized and shaped to fit the outer surface of a bearing assembly and includes a main body having two partial sections connectable by a lateral closure such as a zipper. Each partial section defines an outwardly projecting portion that corresponds with the bearing assembly's shaft. The two partial sections are joined to surround and protect a bearing assembly, including the adjoining shaft portions. The covered assembly can be further protected from the environment by applying a sealant to the closure device, and to the interface between the cover and shaft.
