Abstract
A bearing includes a first ring, a second ring, at least one row of axial rolling elements, and at least one row of radial rolling elements arranged between axial raceways provided on the rings. The second ring has a protruding nose engaged into an annular groove of the first ring and provided with the axial raceway of the second ring. The bearing further includes at least one thrust ring delimiting a radial raceway for the axial rolling elements, and at least one spring system to axially push the thrust ring. The thrust ring is axially disposed between the axial rolling elements and the nose. The spring system is mounted on the nose. The groove of the first ring delimits a radial raceway for the axial rolling elements.

A rolling bearing comprising:
- a first ring,
- a second ring,
- at least one row of axial rolling elements arranged between the first ring and the second ring, and
- at least one row of radial rolling elements arranged between axial raceways provided on the rings, the second ring comprising a protruding nose engaged into an annular groove of the first ring and provided with the axial raceway of the second ring,
- at least one thrust ring delimiting a radial raceway for the axial rolling elements, and
- at least one spring system to axially push the thrust ring against the axial rolling elements, wherein
- the thrust ring is axially disposed between the axial rolling elements and the nose of the second ring and the spring system is mounted on the nose, the groove of the first ring delimiting a radial raceway for the axial rolling elements, wherein a radius is provided between the radial raceway of the groove of the first ring and an axial cylindrical surface of the groove, the radial raceway, the radius and the axial cylindrical surface of the groove being hardened.
