The sealing unit being mounted in the inlet opening to be slidably engaged by the stem and provided with an annular stiffening insert and a flexible annular body provided with two dust-cover lips arranged in sliding contact with the stem, and with a cylindrical static sealing element forcibly and elastically locked inside the inlet opening. The cylindrical static sealing element being radially delimited outwardly by a cylindrical assembly surface having a respective axis (X) of symmetry, which is eccentric with respect to the axis (Y) of symmetry of the first dust-cover lip to ensure a uniform sliding contact of at least the first dust-cover lip on the stem.
