Abstract

L’invention concerne un roulement (100) pour mécanisme horloger (1000) ou médical, comprenant :- une bague extérieure (6),- une bague intérieure (2, 4),- des corps roulants (5, 5’) disposés entre la bague extérieure (6) et la bague intérieure (2, 4). Selon l’invention, au moins une bague (6 ; 2, 4) est réalisée en superalliage austénitique amagnétique. Le roulement selon l’invention a une meilleure résistance aux chocs par rapport aux solutions connues. Figure à publier avec l’abrégé : Fig. 3
