<p>A tapered bearing unit comprises a non-rotating outer race (11), a pair of inner, rotating half-races (12a, 12b), and two sets of rollers (15a, 15b). The bearing unit (10) is equipped with a device (17, 19) for measuring relative rotational speed between the rotating and the non-rotating races. The measuring device comprises an impulse generating ring (17) integral with a rotating part and facing a sensor (19) mounted to a non-rotating part. The measuring device (17, 19) is mounted in an axially intermediate position between the two sets of rollers (15a, 15b). <IMAGE></p> |
