Abstract

L’invention concerne un palier à roulement comprenant un espace de roulement (3) dans lequel au moins une rangée (4a, 4b) de rouleaux sphériques (4) retenue par une cage (5, 5a, 5b) formée d’au moins deux segments indépendants (10, 10a, 10b) disposés bord à bord pour former une cage (5, 5a, 5b) de géométrie annulaire, chacun desdits segments présentant un tronçon (16a) de première couronne (6), un tronçon (16b) de deuxième couronne (7) et au moins deux ponts (8) entre lesdits tronçons, le palier comprenant un anneau (12) qui entoure ladite cage pour maintenir la disposition annulaire bord à bord des segments (10, 10a, 10b), ledit anneau présentant un paroi extérieure (12a) qui est en contact avec l’organe extérieur (1) afin d’assurer le guidage de la cage (5, 5a, 5b) dans l’espace de roulement (3).
