Abstract
A rolling bearing assembly device comprising an outer race, an inner race, a row of rolling elements arranged between the outer and inner races, a sleeve mounted in the bore of the inner race, and an elastic preload element capable of applying an axial preload transmitted to the inner race. The elastic preload element is mounted in direct contact with an annular axial centering portion and bearing axially over its entire periphery against a radial bearing flange extending radially from the axial centering portion towards the outside of the device.

A rolling bearing assembly device comprising:
- an outer race;
- an inner race;
- a row of rolling elements arranged between the outer and inner races;
- a sleeve mounted in a bore of the inner race, the sleeve including an annual axial centering portion arranged in the bore and a radial bearing flange extending outwards from one end of the axial centering portion, the radial bearing flange providing a substantially oblique surface in direct contact with an exterior surface of the inner race;
- and
- an elastic preload element separate from the sleeve, the elastic preload element mounted in direct contact with the annual axial centering portion and capable of applying an axial preload transmitted to the inner race,
- wherein the elastic preload element provides a first radial surface which bears axially over its entire periphery against a radial surface of the radial bearing flange which is an opposite surface to the substantially oblique surface, and
- wherein the radial bearing flange is positioned between the elastic preload element and the exterior surface of the inner race.
