Abstract: A roller bearing includes inner and outer rings each having a raceway, an annular space between the raceways, and a plurality of rolling elements and a lubricating grease in the annular space. The raceways have a predetermined roughness value within a first predetermined range, and the lubricating grease contains graphene particles uniformly dispersed in a suspension in the lubricating grease. The graphene particles have an at least substantially circular shape, a diameter within a second predetermined range and a thickness within a third predetermined range. An amount of the lubricating grease in the annular space and the first, second and third predetermined ranges are selected such that a self-regenerating mat of graphene that at least partially coats the raceways will develop in use as a result of a relative rotation between the inner and outer rings and the rolling/sliding of the rolling elements on the raceways.

Abstract: A bearing device for a vehicle wheel, which has an increased number of balls and in which the ease of mounting the balls is increased. The bearing device is configured such that each of the columns (7b) of the retainer (7) is provided with latch sections (7e) protruding toward adjacent columns (7b) and with cutouts. The front ends of the latches (7e) are located within an annular range having a radial width R1 defined between the outer peripheral circle of a ball (8) and a reference imaginary circle C1 having a diameter D1 centered on the center of the ball (8).

Abstract: A wheel hub bearing unit includes a hub rotatable about an axis and having a flange connectable with a wheel, an inner ball raceway and an inner roller raceway. An outer ring is connectable with the vehicle and disposed about the hub and has an outer ball raceway and an outer roller raceway. A plurality of balls roll upon the inner and outer ball raceways and a plurality of tapered rollers roll upon the inner and outer roller raceways. A difference between a ball pitch circle radius and a roller midpoint circle radius is no greater than five millimeters. A vertex at the intersection of each line extending through the midpoint circle and a line extending through a midpoint of a spacing line segment is spaced from the axis by a radial distance, a ratio of the vertex radial distance to the midpoint circle radius is between 1.5 and 3.0.

Abstract: In one aspect of the present disclosure, a wheel hub assembly is provided that includes a hub body having an outboard end portion and an inboard end portion, a bearing assembly, and a seal. The seal includes a seal case and a sleeve. The hub body and seal case are rotatable relative to the sleeve. The wheel hub assembly further includes a stop of the bearing assembly configured to resist movement of the sleeve toward the outboard end portion of the hub body as the hub body, bearing assembly, and sleeve are advanced together in an inboard direction along a vehicle spindle. The stop permits the bearing assembly to transfer a force applied in an inboard axial direction against the bearing assembly, such as by tightening of a spindle nut, to the sleeve and urge the sleeve along a vehicle spindle.
