Abstract

L'invention concerne une cage de roulement en deux parties pour un roulement à billes, comprenant un premier et un second corps annulaires (1a, 1b) présentant sur leurs surface frontales se faisant mutuellement face une pluralité de coquilles de maintien (2), les deux corps annulaires (1a, 1b) étant conçus identiques et pouvant être montés face à face de telle manière que les coquilles de maintien (2) forment des poches (3) pour le logement et le guidage de corps de roulement (4), le nombre de poches (3) correspondant au nombre de corps de roulement (4). Selon l'invention, les poches individuelles (3) sont espacées mutuellement dans la direction périphérique de telle manière qu'entre deux poches (3) se forme un espace libre (5) pour la réception de lubrifiant, deux coquilles de maintien (2) formant avec une base de poche une poche individuelle (3). L'invention concerne par ailleurs un roulement à billes comprenant une telle cage de roulement en deux parties.
