Abstract

La présente invention concerne un assemblage (15) muni d’un organe tournant (20) et d’au moins un système de roulement (35) double pour assurer un guidage en conditions dégradés. Ce système de roulement (35) comprend une pluralité de premiers éléments roulants (45) ainsi qu’une première piste interne (41) et une première piste externe (42), chaque premier élément roulant (45) étant en contact avec la première piste interne (41). Le système de roulement (35) comporte un deuxième sous-ensemble (50) ayant une pluralité de deuxièmes éléments roulants (55) ainsi qu’une deuxième piste interne (51) et une deuxième piste externe (52), un premier espace (101) séparant chaque deuxième élément roulant (55) de ladite deuxième piste interne (51) en l’absence de défaut du premier sous-ensemble (40), chaque deuxième élément roulant (55) étant adapté pour rouler sur la deuxième piste interne (51) seulement en cas de casse du premier sous-ensemble (40).
