Abstract

L’invention propose un palier de roulement comprenant : - une bague interne et une bague externe coaxiales selon un axe de rotation et entre lesquelles sont disposés des éléments roulants (16), - une cage annulaire (100) de roulement centrée autour de l’axe de rotation et agencée entre la bague interne et la bague externe, la cage annulaire présentant une face annulaire externe (102), en regard de la bague externe et une face annulaire interne (104) en regard de la bague interne,dans lequel la cage annulaire comprend une pluralité de logements (106) logeant les éléments roulants, et au moins l’une de la face externe ou de la face interne comprenant au moins une portion centrale (112) ; ladite au moins une portion centrale (112) est formée par une première surface (1141) et une seconde surface (1142) inclinées par rapport à l’axe de rotation dans un plan longitudinal passant par l’axe de rotation de sorte à faire circuler un fluide de lubrification dudit palier depuis le premier bord annulaire latéral et le second bord annulaire latéral vers une zone de fond (120) de ladite au moins une portion centrale.
