Sealing device, in particular for a rolling bearing and associated

A sealing device insertable between inner and outer rings of a rolling bearing, the sealing device comprising:

• an elastomeric annular sealing element having a radially outer peripheral portion, a radially middle portion, and a radially inner peripheral portion, the radially inner peripheral portion having at least one annular sealing lip on a radial inside of the radially inner peripheral portion, the radially middle portion including an annular housing having a bottom wall delimiting a first face of the elastomeric annular element, the annular housing having a radially outer first annular sidewall and a radially inner second annular sidewall, the first and second annular sidewalls facing one another, the bottom wall being flanked by the first annular sidewall and by the second annular sidewall, the annular housing also having a first annular edge and an annular inlet opening on the side opposite to the bottom wall, the annular inlet opening being bounded radially on the outside by the first annular edge, the first annular edge projecting radially inwards from the radially outer peripheral portion and facing the bottom wall;
• and
• an annular support integrally coupled to the elastomeric annular sealing element so as to be at least partially arranged inside the elastomeric annular sealing element in the radially middle portion, the annular support being bounded between the radially outer peripheral portion and the radially inner peripheral portion of the elastomeric annular element, the annular support being an annular washer made of a synthetic plastic material, the annular support being snap-engaged, without adhesives, with the elastomeric annular element, the annular support being disposed with radial interference within said annular housing and axially clamped between said bottom wall and said first annular edge so as to totally fill the annular housing.
