Abstract
The sealing device (1) for a bearing (2) includes a first piece (8) of annular overall shape secured to the non-rotating race (4) of the bearing and supporting a permanent magnet (14), a second piece (9) of annular overall shape secured to the rotating race (3) of the bearing and including an annular part forming a pulse generator and a flexible sealing part in contact with the first piece. In operation the first and second pieces (8, 9) mounted in the radial space between the rotating race and non-rotating race at one end of the bearing provide the sealing of the bearing with respect to the external surroundings, the permanent magnet (14) being arranged facing a sensor (11) which is fixed with respect to the non-rotating race, the pulse generator passing between the permanent magnet and the sensor during the rotation of the rotating race of the bearing.
