Abstract

L'élément comprend un manchon extérieur de forme tubulaire, des billes 3 étant disposées dans des chemins fermés de circulation pratiqués dans une cage tubulaire intérieure 5, le manchon présentant dans son alésage des secteurs de travail 6 assurant le contact des billes entre l'arbre 1 et le manchon et des secteurs de dégagement 7 permettant la circulation de retour des billes, l'élément comportant sur toute sa longueur une partie coupée selon un plan parallèle à l'axe de l'élément, le plan de coupe déterminant sur la surface extérieure du manchon deux génératrices qui forment avec le centre ou l'axe de l'élément un angle alpha plus petit que 135 degrés . Utilisation : montage à déplacement linéaire à faible encombrement dans la mécanique de précision.
