Abstract

Le segment de cage pour roulement, comporte une portion centrale (16) s’étendant dans le sens circonférentiel et délimitant une pluralité de poches traversantes pour la réception de rouleaux, la portion centrale (16) comprenant des première et deuxième parois (49) s’étendant dans le sens circonférentiel, et pourvues de surfaces intérieures (20, 22) en regard l’une de l’autre et formant des surfaces de butée pour les faces d’extrémités des rouleaux. Il comprend en outre un premier rebord latéral (24) prolongeant vers l’extérieur la première paroi (49) de la portion centrale et un deuxième rebord latéral (26) prolongeant vers l’extérieur la seconde paroi de la portion centrale en étant orienté perpendiculairement au premier rebord latéral, au moins un évidement (30) ouvert vers l’extérieur étant formé sur chacun des premier et deuxième rebords latéraux.
