The method concerns the manufacturing of a target holder for sensor bearing unit, having a preliminary step of manufacturing a metal sheet, and a step of manufacturing the target holder. The manufacturing step of the target holder includes a forming operation of the target holder from the manufactured metal sheet providing the target holder with at least an axial fixing portion intended to be secured to a ring of the sensor bearing unit, and with a radial portion extending at least radially with respect to the axial fixing portion, a curved linking portion being formed between the axial fixing portion and the radial portion. At least one of the manufacturing steps comprises a surface roughening operation providing a surface roughness value ranging between 0.05 μm and 0.95 μm.

Sensorised wheel hub unit and a method for detecting, in real time, forces and moments applied to an outer ring of the wheel hub unit in which piezoresistive ceramic plates are made of one piece with welded metal plates housed within respective recesses formed in an outer surface of the outer ring over respective races for rolling elements in such a way that there is a gap between the plates and a base wall of each recess; in which the temperature of the outer ring and the amplitude and frequency of first electrical signals (S1) associated with the sensors relating to the same race are analysed to determine a frequency value equal to the frequency of the first signal having the maximum amplitude and as many amplitude values (D1-Dn) as there are sensors associated with that race and each equal to the maximum amplitude of the first signal from each sensor, corrected according to the temperature.

A bearing unit having an axis of rotation (X) for a wheel hub assembly for motor vehicles includes stationary radially outer ring, a rotatable wheel hub or first radially inner ring, a rotatable second radially inner ring having an axially external first axial contact edge, an axially internal second axial contact edge having a radially external first contact surface configured to abut a surface of the first radially inner ring, a radially internal second contact surface, and a relief groove interposed radially between the first contact surface and the second contact surface, two rows of rolling bodies interposed between the radially outer ring and the second radially inner ring, and a joint including a bell, the second contact surface contacting a surface of the bell and axial locks the radially inner ring, and the relief groove reducing contact between the second contact edge and the surface of the bell.

An integrated seal and bearing assemblies with a bearing assembly having an outer ring defining an outside diameter of the bearing assembly and an inner ring defining an inside diameter of the bearing assembly, and having a plurality of rolling elements located between the inner and outer rings. A seal assembly having a sealing element is integrated with the bearing assembly by engaging an extended flange with an internal channel of the seal element, with a sealing extended flange, or directed with complementary surfaces of the outside flange.

Bearing for a shed-forming machine or a system for transmitting movement to the frames of a loom, which has an inner ring, an outer ring and rolling elements. The inner ring is centered on a major axis, has two lateral surfaces normal to the major axis, and defines a circular peripheral path centered on the major axis. The outer ring defines an inner path, which is circular and centered on the main axis. The rolling elements are interposed, radially with respect to the main axis, between the peripheral ring and the inner ring, to guide the outer ring in rotation relative to the inner ring around the main axis. The inner ring has at least one slot, opening onto the two lateral surfaces, extending opposite a portion of the peripheral path, and forms a bridge of material between the slot and the peripheral path.

An input gear assembly in which the input gear is coupled to the input shaft via a pair of spaced-apart pilot regions of the input shaft. One of the pilot regions is disposed adjacent to one of the bearings used, with the pilot region formed in or on the input shaft itself and engaging a corresponding internal surface of the input gear. Another of the pilot regions is formed in the inner bearing raceway of another of the bearings used, with the pilot region formed as an elongate portion of the inner bearing raceway of the input shaft and engaging another corresponding internal surface of the input gear. For manufacturing simplicity, this additional pilot region and the remainder of the elongate inner bearing raceway have the same material properties, surface treatment, straightness, and cylindricity. This arrangement prevents tilting of the input gear with respect to the input shaft and bearing shaft, thereby enhancing performance.

A bearing providing a first ring assembly and a second ring assembly, the first ring assembly including at least a first ring and an outer cap reversibly fixed to first ring. The bearing further providing at least one sealing element mounted radially into a cylindrical surface of the first ring assembly and provided with a sealing lip in sliding frictional contact with the second ring assembly. The bearing including at least one adjusting shim mounted radially between the first and second ring assemblies, the adjusting shim being axially located between the outer cap of the first ring assembly and the sealing element; or between the first ring of the first ring assembly and the sealing element.

The bearing provides a first ring and a second ring centered on an axis, each of the first and second rings being provided with an outer cylindrical surface, with an inner cylindrical surface, and with lateral faces that axially delimit the outer and inner cylindrical surface. One of the inner and outer cylindrical surfaces and/or one of the lateral faces of the first ring includes a textured area provided with a groove extending circumferentially and with two protrusions disposed one on each side of the groove and extending along the groove.

To provide an insulating rolling bearing that is capable of preventing electrolytic corrosion and preventing a gap from being undesirably formed between a shaft and a raceway ring. A sub bearing 21 includes an inner ring 22, an outer ring 23, balls 24 interposed between the inner ring and the outer ring, and an insulating bushing 28 fitted to an inner peripheral portion of the inner ring 22. The insulating bushing 28 includes a generally cylindrical metal base 28a, and a resin layer 28b formed on an inner peripheral surface of the metal base 28a. The insulating bushing 28 is fitted to the inner peripheral portion of the inner ring 22 such that the metal base 28a abuts on the inner peripheral portion of the inner ring 22.

A rolling bearing has an inner and an outer bearing ring. Each bearing ring has an inner and an outer shell surface. The roller bearing has rolling elements, which roll on raceways provided on the respective shell surfaces of the bearing rings, and a sealing disc connected to one of the bearing rings and operatively connected in a sealing manner to the other bearing ring. To connect the sealing disc to the bearing ring, one of the shell surfaces of the one bearing ring includes a first connecting means and the sealing disc includes a second connecting means. The first connecting means provide a rotating engagement in which the second connecting means engage in a connected state of the bearing ring and the sealing disc.
