Abstract

Dispositif d'étanchéité (1) pour une unité de roulement (10), dans lequel l'unité comprend une bague radialement extérieure (11), deux rangées d'éléments de roulement (12, 13) interposées, respectivement, entre la bague radialement extérieure (11) et une paire de bagues radialement intérieures (14, 15). Le dispositif d'étanchéité comporte une entretoise (20) pourvue d'une gorge annulaire (21) et configurée pour être interposée entre les bagues radialement intérieures (14, 15) de l'unité de roulement (10) et un joint (30) logé à l'intérieur de la gorge (21) de l'entretoise (20), dans lequel le joint (30) présente une forme en "U" qui délimite un volume en son intérieur et est configuré pour être monté dans la gorge annulaire (21) avec la concavité (31) tournée vers l'axe de symétrie de l'unité de roulement.
