Abstract
A rolling bearing includes first and second rings each having an axial raceway and a radial raceway and axial rolling elements between the radial raceways and radial rolling elements between the axial raceways, the second ring having a protruding nose extending into an annular groove of the first ring, the nose having an axial cylindrical surface that forms the axial raceway of the second ring. Also at least one ultrasonic distance sensor mounted on the first ring in radial contact with the axial cylindrical surface of the nose and configured to emit radiation in a main radiation direction oriented towards a surface of the second ring that is inclined relative to a rotation axis of the rolling bearing.
