Sealing device (1) for a wheel hub group (2) which is connected to a
differential device, and which is provided with a rolling contact bearing
(3), the sealing device being provided with a first shield (6) which is
shrink-fit onto an inner race (4) of the rolling contact bearing (3), and
an encoder (7) which is integral with the first shield (6) in order to
generate a signal for reading the functioning kinematic parameters of the
wheel hub group (2), and is also provided with a second shield (8) which
is shrink-fit onto an outer race (5) of the rolling contact bearing (3)
in a position which is opposite to and which is also external to the
inner shield; a static sealing element (12) is integral with the second
shield (8), and is also arranged in contact with a containing box of the
differential in order to define a watertight chamber (14) in order to
provide a reading surface of a reading sensor (11) which can read the
signal which is generated by the encoder itself.
