A bearing (LAG) for bearing a torsion bar spring (DSF) of a roll stabilization system of a track vehicle comprises a split bearing bush (LAB) for the torsion bar spring and a split bearing shell (LAS) which comprises said bearing bush and which can be connected to the body/bogie. A pair of seals (ADI, IDI) is mounted at one end of the bearing (LAG) and consists of an inner, flexible inner seal (IDI) sitting on the torsion bar spring (DSF) and an outer, flexible outer seal (ADI) sitting in the bearing shell (LAS). Every seal of the pair of seals comprises at least one peripheral sealing lip (DI1, DI2; DAL) and the seals interact with each other via the sealing lips in a sealing manner.

La présente invention concerne un palier (LAG) sur lequel prend appui une suspension à barre de torsion (DSF) du système anti-roulis d'un véhicule ferroviaire, comprenant un coussinet (LAB) en plusieurs parties destiné à la suspension à barre de torsion, et une coquille de coussinet (LAS) en plusieurs parties entourant le coussinet et pouvant être reliée à la carrosserie du véhicule ou au bogie. Sur au moins un côté d'extrémité du palier (LAG) se trouve une paire d'éléments d'étanchéité (ADI, IDI) qui consiste en un élément d'étanchéité intérieur (IDI) flexible, reposant sur la suspension à barre de torsion (DSF), et un élément d'étanchéité extérieur (ADI) flexible reposant dans la coquille de coussinet (LAS), chaque élément d'étanchéité de la paire présentant au moins une lèvre d'étanchéité (DI1, DI2; DAL) périphérique, et les éléments d'étanchéité coopérant par l'intermédiaire des lèvres d'étanchéité pour assurer l'étanchéité.
