Abstract

Roulement à rangées sans fin d'éléments roulants guidées dans des canaux pourvu d'au moins un élément de cheminement qui comporte, pour les élements roulants chargés de la rangée sans fin, une cannelure longitudinale adaptée à leur contour. L'élément de cheminement 1 présente à l'entrée et/ou la sortie de la cannelure 4 une surface frontale en biseau s'étendant, longitudinalement vers l'intérieur, de l'arête 10 faisant vis-à-vis à l'arbre au moins jusqu'au fond de ladite cannelure 4. Application : guidage longitudinal sur un arbre.Bearing with endless rows of rolling elements guided in channels provided with at least one routing element which comprises, for the rolling elements loaded with the endless row, a longitudinal groove adapted to their contour. The routing element 1 has at the entrance and / or exit of the spline 4 a beveled front surface extending, longitudinally inwards, from the edge 10 facing the shaft at least to the bottom of said groove 4. Application: longitudinal guidance on a shaft.
