1. 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.
 
9. 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, wherein
the spring system is mounted into a hole provided on the nose of the second ring, and wherein
the nose of the second ring is provided with an axial cylindrical surface onto which is formed the axial raceway of the second ring.
