The sealing device (8) for the passage of a fluid between a rotating race and a non-rotating race of a bearing each penetrated by channels (6, 7) for the passage of the fluid, comprises a one-piece annular central body (9) of elastic material having a circular shoulder (10) for fixing to one of the races (1), and two main sealing lips (12) which mutually form an annular intermediate chamber (13) and which are in friction contact with the other race (2). The central body (9) is penetrated by at least one channel (15) communicating with the channels (6) of the race associated with the circular fixing shoulder, and also with the intermediate chamber, which communicates with the channels (7) of the other race, so that the fluid introduced into the channels of one of the races of the bearing passes through the central body in a leaktight manner and exits through the channels of the other race.
