High flexibility sealing device, in particular for household appliances

A sealing device for protecting a rolling bearing of a household appliance, the sealing device exerting a static hydraulic sealing action between two mechanical elements arranged facing each other and spaced apart by a variable axial distance, the sealing device comprising:

• a substantially rigid annular support element including a radially outer sleeve portion;
• and
• an annular elastomeric element integrally formed with the annular support element, having an axis of symmetry and including an elastically deformable, first annular sealing lip extending cantilevered from the outer sleeve portion of the support element, the first annular sealing lip having a first branch projecting radially from the sleeve portion of the support element in a direction away from the axis of symmetry and a second branch extending from a free end of the first branch in a direction both axially away from the support element and radially toward the axis of symmetry, the first and second branches being arranged at an angle relative to each other so as to form in radial cross-section a V-shape oriented radially converging in a direction away from the axis of symmetry of the elastomeric annular element and constituting adjacent annular portions of the first sealing lip.
