Abstract

L’invention concerne un ensemble de roulement (1) à éléments roulants cylindriques (2) comprenant une bague intérieure (3), une bague extérieure (4), et une pluralité d’éléments roulants cylindriques (2) arrangés radialement entre les pistes de roulement interne (5) et externe (9). La bague intérieure (3) comprend un épaulement annulaire (6) en saillie par rapport à la piste de roulement interne (5), un congé de raccordement (8) en arc de cercle étant défini entre lesdits épaulement annulaire (6) et piste de roulement interne (6). La bague extérieure (4) comprend un épaulement annulaire (10) en saillie par rapport à la piste de roulement externe (9), ledit épaulement annulaire (10) de la bague extérieure (4) étant logé axialement entre l’épaulement annulaire (6) de la bague intérieure (3) et les éléments roulants cylindriques (2). Ledit épaulement annulaire (10) de la bague extérieure (4) est pourvu d’un chanfrein annulaire (13) venant à proximité immédiate dudit congé de raccordement (8) défini à la bague intérieure (3).
