Abstract
Cet élément comprend, selon l'invention un manchon extérieur 1 et une cage 4 présentant des chemins de circulation fermés, dans lesquels circulent des billes 2, le manchon 1 présentant dans son alésage des secteurs de travail 5 assurant le contact des billes 2 entre l'arbre et le manchon et des secteurs dégagés radialement 8 permettant la circulation de retour des billes, la cage 4 comportant sur sa surface extérieure des bossages longitudinaux 9 en forme de cannelures positives sur toute la longueur de ladite cage 4 et venant se prendre avec précision dans les rainures de forme correspondante pratiquées longitudinalement dans l'alésage du manchon et servant aussi à la décharge de roulement le long du rectiligne de retour des billes, des moyens 13, 14 étant prevus pour arrêter longitudinalement la cage 4 par rapport au manchon 1. On peut ainsi obtenir des déplacements linéaires illimités sur un arbre dans la mécanique de précision.
