A rolling-contact bearing has a speed-detecting device which includes a sensor which is fixed to a non-rotating race of the bearing, and an encoder element which is mounted on a subassembly which includes two rotating races. The rolling elements of the bearing are held by two axially spaced cages. The encoder element has an active part and a radial part which supports the active part. The radial part extends between the two cages. The active part of the encoder element has an axial dimension which is greater than the axial distance between the two cages.
