1. An instrumented rolling bearing device comprising:

  • a non-rotating race provided with a raceway;

    a rotating race provided with a raceway;

    at least one row of rolling elements arranged between said raceways of the rotating and non-rotating races;

    an assembly for detecting rotation parameters comprising a non-rotating sensor assembly and a rotating encoder; and

    an elastic member intended for axially prestressing the rolling bearing, retained axially on the sensor assembly, the elastic member being of annular shape and having an outer diameter smaller than or equal to that of the outer race of the bearing, the elastic member comprising a supporting surface designed to be in contact with an element outside said bearing device in order to exert, directly or indirectly, by reaction from the above element outside said device, an axial force on the non-rotating race in a direction opposite to the detection assembly.
