Abstract: An asymmetric wheel hub assembly with two rows of rolling elements of different pitch diameters has a central axis of rotation and inner raceway and outer raceways for each row of elements, the associated inner and outer raceways being axially displaced in accordance with a respective angle of contact and along a respective load line such that the assembly is capable of accommodating combined loading. The raceways of each row of rolling elements have osculation ratios which are defined by the ratio between the radius of curvature of the raceways and the outside diameters of the rolling elements of the associated row of rolling elements. The angle of contact and the osculation ratios of a first one of the two rows of the rolling elements is different than the angle of contact and osculation ratios of a second one of the two rows of the rolling elements.

Abstract: The invention concerns a method for manufacturing a ceramic material with pseudo-isotropic microstructure. The method for tailoring the microstructure for manufacturing of sintered ceramic components involves a spark plasma sintering (SPS) process. By performing the SPS process in at least two steps it is possible to separate densification from grain growth. An initial sintering step at a first temperature and a first pressure, followed by a controlled grain growth step at a higher temperature and lower pressure makes it possible to manufacture ceramic components with controlled microstructure and improved mechanical properties.

Abstract: A rotation sensor (19) is used for detecting relative rotation between a rotatable member (11, 12) and a non-rotatable member (10) of a bearing unit. The sensor (19) is retained in a sensor carrier body (18) of plastic material and annular shape. An annular supporting insert (17) serves to mount the sensor carrier body (18) onto the non-rotatable member (10) with the sensor operatively facing an impulse ring (15) secured to a rotatable member (12) of the unit. The sensor carrier body (18) and the supporting insert (17) provide a lock and seats (18a, 18c, 18d, 18m, 18n; 17c, 17d, 17m, 17n) for releasably locking the sensor carrier body (18) to the supporting insert (17).

The thrust washer including a first annular upper ring having first inner and outer side circumferential surfaces and first top and bottom surfaces. The upper ring providing at least two holes that extend therethrough the first top and bottom surfaces and a first annular lower ring having second inner and outer side surfaces and second top and bottom surfaces. The first lower annular ring includes at least two annular projections extending upward from the second top surface. The at least two annular projections align with the at least two holes to create an interlocking fit between the first annular upper and lower rings. The interlocking fit allows the first upper and lower rings to combine and function as the single element thrust washer 10 once interlocked together. The interlocking fit further prevents any rotation between the first upper and lower annular rings during operation.
