The invention relates to a shaft seal comprising an inner sealing element (6) which is arranged on an axle shaft (2) and has at least one ring (7, 9, 11), and an outer sealing element (13) which is arranged on a roller body (1) and has at least one ring (14, 15, 16) which is oriented essentially parallel to the at least one ring (7, 9, 11) of the inner sealing element (6). According to the invention, a ring (14, 15, 16) of one of the two sealing elements (13) is provided with an annular projection (17, 18, 19) facing a ring (7, 9, 11) of the other sealing element (6), said projection being in contact with the ring (7, 9, 11) of the other sealing element (6) during the assembly of the shaft seal and being ground, once the axle shaft (2) and/or roller body (1) has started to rotate, until a narrow ring gap between the projection (17, 18, 19) and the ring (7, 9, 11) of the other sealing element (6) is formed.
L'invention concerne un joint d'arbre comprenant un élément d'étanchéité (6) interne qui est disposé sur un arbre de commande (2) et présente au moins une bague (7, 9, 11), ainsi qu'un élément d'étanchéité (13) externe qui est disposé sur un corps de rouleau (1) et présente au moins une bague (14, 15, 16) sensiblement parallèle à la bague (7, 9, 11) de l'élément d'étanchéité (6) interne. Selon l'invention, une bague (14, 15, 16) d'un des deux éléments d'étanchéité (13) présente une partie saillante (17, 18, 19) annulaire faisant face à une bague (7, 9, 11) de l'autre élément d'étanchéité (6). Lorsque le joint d'arbre est monté, cette partie saillante (17, 18, 19) est en contact avec la bague (7, 9, 11) de l'autre élément d'étanchéité (6) et lorsque l'arbre de commande (2) et/ou le corps de rouleau (1) commencent à tourner, ladite partie saillante (17, 18, 19) est rectifiée jusqu'à ce que l'espace annulaire entre celle-ci et la bague (7, 9, 11) de l'autre élément d'étanchéité (6) soit réduit.
