Integrated bearing intended particularly for equipping a motor-vehicle wheel hub, comprising a rotary outer ring (1) and a stationary inner ring (2); at least one row of rolling elements (3) arranged between the outer and inner rings; an annular pulser (4) fixed to the rotary ring (1) in the vicinity of one of its ends; and a sensor (5) stationary relative to the stationary ring (2) and located opposite the pulser so as to be capable of measuring the rotational speed of the outer ring in relation to the inner ring of the bearing, characterized in that it comprises a substantially annular flange (6) delimited by an inner cylindrical rim (6a) fixed to the inner ring (2) and by an outer cylindrical rim (6b) which is coaxial relative to the inner rim and on the outside of which is mounted a sensor carrier (7) equipped with means (16) for fastening a connecting cable (8) connected to the sensor, the flange covering without contact the end of the outer ring (1) where the pulser is fastened and being equipped with an orifice (6c), through which the sensor is mounted opposite the pulser.
