Abstract
A sealing device for a sleeve of washing machines, provided internally with bearing units. The device is provided with a stationary first annular screen which integrally carries a first elastomeric element, a second annular rotating screen which integrally carries a second elastomeric element. The first and the second elastomeric elements face each other defining a first annular meatus (M), and a plurality of pairs of annular sealing lips (L, L) arranged inside the first annular meatus (M). The first sealing lip (L) and the second sealing lip (L) of the plurality of pairs of annular sealing lips (L, L) are substantially radially and axially superimposed and have predetermined axial dimensions to be radially and axially separated from each other and to define, inside the first annular meatus (M) and with the first and second sealing lips of the other pairs of annular sealing lips (L, L), a tortuous labyrinth (L).
