Abstract

a. Elément de liaison possédant une surface d'étanchéité entourée de surfaces ayant des propriétés différentes. b. Elément de liaison caractérisé en ce qu'il comprend une première surface d'étanchéité pouvant coopérer avec un joint pour retenir un lubrifiant et une seconde surface immédiatement adjacente à ladite première surface d'étanchéité, ladite surface d'étanchéité ayant une plus grande dureté que ladite seconde surface adjacente, ces deux surfaces étant faites d'une même matière c. Concerne des éléments de liaison mécaniques, en général, et plus particulièrement les coussinets d'articulation des maillons des chemins de roulement pour véhicules à chenilles.at. A connecting element having a sealing surface surrounded by surfaces having different properties. b. Connecting element characterized in that it comprises a first sealing surface which can cooperate with a seal to retain a lubricant and a second surface immediately adjacent to said first sealing surface, said sealing surface having a greater hardness than said second adjacent surface, these two surfaces being made of the same material c. Relates to mechanical connecting elements, in general, and more particularly to the articulation bearings of the links of the raceways for tracked vehicles.
