Abstract: A magnetic impulse ring having a central axis that includes a target holder and a target that is fixed to the target holder. The target provides a plurality of alternating South and North magnetic poles. The target is adapted to cooperate with magnetic detection means for tracking the rotation of the magnetic impulse ring around its central axis. The Total Pitch Deviation (TPD) of the magnetic impulse ring is less than or equal to 0.5%.

Abstract: A combined electrical insulator and conductor assembly for a bearing disposable between a shaft and a housing. An annular insulator is disposeable about the bearing and configured to prevent electric current flow between an outer ring and the housing. An electrical conductor has retainer(s) releasably engaged with the insulator so as to couple the conductor with the bearing, an outer radial end and an inner radial end. The conductor outer radial end, or/and a portion of the conductor between the outer and inner ends, is conductively engageable with the housing and the conductor inner radial end is conductively engageable with the shaft so as to provide an electrically conductive path between the shaft and the housing. Preferably, the conductor includes a conductive disk having arcuate retainer clips engageable with an insulator groove of the insulator and a brush subassembly including conductive fibers engaged with the shaft outer surface.

Abstract: A combined insulator and conductor assembly for a bearing disposable between a shaft and a housing includes an annular insulator disposeable about the bearing outer ring and having inner and outer circumferential surfaces and formed of an electrically insulative material or having one or more insulative layers to prevent electric current flow between the outer ring and the housing. A conductive carrier includes a cylindrical portion having an inner surface disposed about the insulator outer surface and an outer surface disposeable against the housing inner surface and a disk portion extending radially inwardly from the cylindrical portion having an inner radial end spaced outwardly from the shaft. An annular conductive brush subassembly is coupled with the carrier disk portion and includes a plurality of electrically conductive fibers contactable with the shaft outer surface to provide a conductive path between the shaft and the carrier, and thereafter to the housing.

Abstract: A method of determining bearing preload by vibration measurement including mounting the bearing on a vibration tester, the outer ring clamped preventing rotation, mounting a sensor proximate the outer ring to measure vibration, the bearing inner ring rotated to excavate eigen-frequencies, the measured vibration data transmitted from the sensor to a computer workstation, the computer workstation performs a numerical FFT transforming data to Frequency Domain, spectral data from the FFT analyzed with the computer workstation, a peak detection algorithm determines the peaks that are the various modes of the outer ring, the modes are sorted and main modes identified, numerical relationship is obtained for each mode between the resonance and preload, the mode relationships are compared to one or more references, a match between the numerical relationships for each mode and the ideally referenced graph modes indicates a correct preload is determined. Also, a system for carrying out the method.

Abstract: An insulating device for a bearing mountable within a housing, the bearing having an inner ring and an outer ring with an outer circumferential surface and opposing axial ends and a plurality of rolling elements disposed there between. The insulating device comprises: a first annular part, which is adapted to be in contact to the outer circumferential surface of the outer ring, and a second annular part, which is also adapted to be in contact to the outer circumferential surface of the outer ring. The first and second part form the insulation device which is adapted to contact, in an assembled state of the bearing in the housing, both the outer ring and the housing. The first part is thermally conductive and electrically insulating and the second part is electrically insulating and less thermally conductive than the first part or is not thermally conductive.

Abstract: A wheel hub bearing for motor vehicles, comprising a hub and a bearing unit in turn comprising a radially outer ring, at least one radially inner ring, at least one crown of rolling bodies between the radially outer ring and the radially inner ring, whereas the hub has a radial stiffening. The radial stiffening of the hub has a misalignment (d) respect to a seat, i.e. a distance between a centerline axis (Y) of the seat of the radially inner ring on the hub and a centerline (Z) of the radial stiffening less than or equal to 25% of a length (l) of the seat.

Abstract: An electrically conductive assembly is for a bearing disposed about a shaft and disposed within a housing. The conductive assembly includes an annular retainer coupleable with a bearing outer ring or with the bearing housing and having a centerline and an open inner end defining an annular groove. At least two and preferably several conductors each have a radially outer end disposed within the retainer groove and a radially inner end contactable with the shaft. Each conductor is formed of a plurality of conductive fibers arranged to extend radially inwardly from the retainer inner end. The at least two conductors are spaced apart circumferentially about the centerline so as to define at least two axial passages between the retainer and the shaft. Preferably, the conductors are separated by spacers formed of conductive fibers each having a length shorter than the length of the fibers of the conductors.
