  • Patent number: 9371862
    Abstract: A bearing assembly for rotatively holding a shaft with respect to a support member and comprises: a bearing, with a rotatable ring and a fixed outer ring to be immobilized within a housing of said support member. An encoder washer is fast in rotation with the rotating ring. At least one sensor is adapted to detect at least one rotation parameter of the encoder washer and a sensor body holds this sensor. An annular flange is used for mounting said sensor body with respect to the fixed outer ring. The annular flange has a first skirt and a second skirt which define, between them and a bottom wall of the flange, an annular recess for accommodating at least a part of the sensor body. In mounted configuration of the bearing assembly, the first and second skirts extend respectively towards the rotatable and fixed rings.
