Abstract
Sealing device for a wheel-hub unit provided with a rolling bearing and having a central axis and being provided with a screen joined together with an outer ring of the bearing to sealingly isolate the bearing and having a cylindrical mounting wall coaxial with the central axis and engaged with a collar of an outer ring of the bearing, and an annular reading wall, arranged transversely with respect to the axis, connected to the cylindrical wall and facing a phonic wheel mounted inside the bearing; the annular reading wall having a thickness variable radially depending on an angle of oscillation of the phonic wheel between an undeformed position. An annular front surface of the phonic wheel is equidistant from a plane perpendicular to the axis, and a possible deflected position, in which the annular front surface of the phonic wheel is arranged equidistant from an annular reading wall.
