The bearing includes an exterior ring (11), two inner rings (12,13), two rows of rolling elements (14), maintained in position by cages (15), and an integrated rotational speed detector (17). The detector is of the type having an encoder (19) arranged in an annular chamber defined between the inner and exterior rings and the rolling elements. The encoder has an active part (20) which creates a periodic frequency signal proportional to the rotational speed of the winding in the detector. The encoder includes a support (21) fixed to the inner rings and made from a non-magnetic material so that it retains the inner rings axially against each other before mounting the bearing into the mechanical assembly for which it is designed. |
