A rolling bearing includes an outer ring, an inner ring, and a plurality of rolling bodies between the rings. The outer ring includes a first and a second annular raceway, both formed on an inner lateral surface of the outer ring, and an axial shoulder extending in a radially inward direction and formed between the two raceways. The axial shoulder includes a first curvilinear portion formed by a first arc of a first circle with a first radius of curvature and a geometric center projected in a radially inward direction, and a second curvilinear portion formed by a second arc of a second circle comprising a second radius of curvature and a geometric center projected in a radially outward direction. The two curvilinear portions are flush connected to one another by an inflection point, the inflection point representing a tangent point of the first and second circles.

In a vehicle suspension assembly a sensorized system applied to a wheel hub unit, in which radially outer cylindrical surface of an outer ring of the wheel hub unit configured for coupling to a suspension upright or knuckle has four circumferential flats formed to be angularly spaced from each other on the radially outer lateral cylindrical surface, each flat delimiting a plane surface which extends axially over a pair of annular tracks for rolling bodies of the outer ring; each flat carries integrally a sensor module including a pair of extensometers positioned parallel to each other and each at the position of a respective annular track, orientated in a circumferential direction so as to extend along a circumferential development of the annular track; an electrical circuit picks up a signal from each sensor module and sends it to a data socket carried by the suspension upright or knuckle.

Sensorized suspension assembly for vehicles, including a wheel hub unit and a suspension upright or knuckle, and an associated method and wheel hub unit

A sealing assembly insertable between a stationary outer ring and a rotating inner ring of a bearing or hub bearing unit, having a first C-shaped shield supported by the inner ring and a second L-shaped shield supported by the outer ring. The first shield has a first annular sealing element having a first annular lip that extends axially cantilevered from the flange portion of the second shield in a position facing a radially outer sleeve shaped portion of the first shield and a second annular lip, elastically deformable, arranged radially on the inside of the first lip and which cooperates in contact with a radially inner sleeve shaped portion of the first shield, which carries a second sealing element having a third annular lip, which extends axially cantilevered from the first shield and towards the second shield and which is radially interposed between the first and the second lip.

Sealing assembly for rolling bearings, in particular for a hub bearing unit of vehicles and associated hub bearing unit

A sealing device including a first annular rotating shield, a second annular shield, fixed and arranged in front of the first shield for delimiting therebetween a first annular chamber and a sealing ring provided with at least a first and a second annular lips that extend axially and radially project from a flange portion of the second shield and towards a flange portion of the first shield, inside the annular chamber. At least one of the first and second lips cooperates with the flange portion of the first shield without touching it for defining a first dynamic labyrinth seal therewith. The first shield integrally supports a third annular lip that extends projecting from the first shield towards one of the first and second lips without touching it for defining a second dynamic labyrinth seal between the first and second shield and inside the annular chamber.

Drip element sealing device, in particular for rolling bearings

A sealing unit having a first annular rotating shield and a second annular shield is provided. The second annular shield is fixed and arranged in front of the first shield for delimiting therebetween a first annular chamber and a sealing ring provided with at least a first and a second annular lips, which extend axially and radially projecting from a flange portion of the second shield and towards a flange portion of the first shield, inside the annular chamber. The first shield integrally supports a third annular lip that extends projecting from the first shield towards one of the first and second lips without touching it for defining a second dynamic labyrinth seal between the first and second shield and inside the annular chamber.

Sealing unit, in particular for rolling bearings

A flanged bearing ring has a tubular core of steel and an outer flange of a light metal in which there are formed axial through bores for accommodating bolts for mounting a wheel to the ring; fixed in each bore is a steel insert which forms a threaded inner cylindrical cavity extending between two opposite faces of the flange, and one or two transverse shoulders which are in contact with the material of the flange so as to oppose relative axial movements of the steel insert with respect to the flange.
