Claim Text:
1. A rolling bearing assembly device having an axis of rotation, comprising: an inner race having a bore and first and second axial ends, an outer race, and at least one row of rolling elements disposed between the inner race and the outer race, and a sleeve mounted in the bore of the inner race, wherein the sleeve being formed as a one-piece integral member, the sleeve having first and second sleeve axial ends and a radial bearing flange, the inner race is completely overlapped by the sleeve in the axial direction, a first portion of the sleeve extending axially away from the inner race and axially away from the first axial end of the inner race to form the first axial sleeve end, a second portion of the sleeve extending axially away from the inner race and axially away from the second axial end of the inner race to form the second axial sleeve end, the radial bearing flange having a bearing surface configured to non-threadably contact a locking washer located adjacent to the first axial sleeve end, the bearing surface extending outwardly radially from the first axial sleeve end and toward the second axial sleeve end to form an oblique surface relative to the axis of rotation, in axial cross section the oblique surface defines a continuous linear path from the first axial sleeve end to a part of the first portion of the sleeve that is at a maximum radial distance from the axis of rotation, the inner race being completely located axially between the part of the first portion of the sleeve and the second axial sleeve end, wherein the second portion of the sleeve that extends axially past the second axial end of the inner race and connects to the second sleeve axial end has a radially outer axially extending surface, the radially outer axially extending surface of the second portion having no radially outward protrusions thereon such that the second portion of the sleeve has a maximum diameter that is less than or equal to a minimum diameter of the inner race, and wherein the sleeve further provides at least one slot extending axially towards the inner race from the first axial sleeve end of the radial bearing flange.
