Un joint d'étanchéité de l'espace intérieur (3) possède une lèvre d'étanchéité (45) à contact étanche frottant. L'objectif de l'invention est d'obtenir un système de palier immergé économique, écologique et simple qui possède de bonnes propriétés d'étanchéité. A cet effet, le contact étanche est formé par deux surfaces coniques adjacentes et par une surface de contact. La première surface conique forme un premier angle α avec la surface de contact et la seconde surface conique forme un second angle β avec la surface de contact (30). Le premier angle α est disposé du côté du milieu d'immersion (4), le second angle β du côté de l'espace intérieur (3), le premier angle α étant plus grand que le second angle β.
