Abstract

Roulement comprenant plusieurs circuits d'éléments roulants en forme de bobine, à surface de roulement concave. Entre les éléments roulants 4 voisins sont disposés des galets de guidage 5, 5' en forme de barillet, qui sont en contact linéaire avec les surfaces de roulement 15 concaves des éléments roulants 4.Bearing comprising several circuits of rolling elements in the form of a coil, with a concave running surface. Between the neighboring rolling elements 4 are arranged guide rollers 5, 5 'in the form of a barrel, which are in linear contact with the concave rolling surfaces 15 of the rolling elements 4.
