Low-friction sealing device and associated rolling bearing

A sealing device for a rolling bearing, comprising:

• a first annular shield configured to be attached, in an angularly integral manner during use, to a component of a radially inner ring of the rolling bearing,
• a second annular shield configured to be attached, in an angularly integral manner during use, to a radially outer ring of the rolling bearing, in a position facing the first annular shield,
• at least one elastomeric sealing element formed integrally as one piece with the second annular shield and having at least one elastically deformable first annular sealing lip that cooperates in interference contact with a slide-contact surface of the first annular shield, and
• an annular static sealing element that is at least substantially sleeve-shaped and is configured to be interposed during use between the first annular shield and the radially inner ring of the rolling bearing and to mate in a fluid-tight manner with a radially outer side of a constant velocity joint,
• wherein:
• the annular static sealing element extends in an axially projecting manner from a first face of the first annular shield, which is opposite the second annular shield and is configured to face the constant velocity joint during use,
• on a radially inward side of a side wall of the annular sealing element, at least one groove is defined and is configured to form a hydraulic communication channel that permits hydraulic communication between a first surrounding volume adjacent to a first front face of the second annular shield, which is opposite to the first annular shield and the elastomeric sealing element, and an empty inner volume of the annular static sealing element bounded by the side wall of the annular sealing element, and
• the groove extends axially beyond the elastomeric sealing element on the side of the first face of the second annular shield.
