Abstract

[Palier pour moteur ou machine électrique] Le palier comprend une bague intérieure 12, une bague extérieure 14, au moins une rangée d’éléments roulants 16 interposés radialement entre des chemins de roulement 24, 26 desdites bagues, et au moins une cage 18 de maintien de l’espacement circonférentiel des éléments roulants pourvue d’un talon 30 annulaire. Le talon 30 de la cage est en retrait axialement vers l’intérieur par rapport à des faces frontales 12c, 14c des bagues intérieure et extérieure, la distance axiale séparant une face frontale 30a du talon d’au moins l’une desdites faces frontales étant comprise entre 4 % et 10 % de la distance axiale entre la face frontale 30a du talon et le plan radial P1 de symétrie des chemins de roulement 24, 26 des bagues intérieure et extérieure.
