Les diam\u00e8tres de tige varient de 6 \u00e0 900 mm, les longueurs atteignant 12\u201318 m\u00e8tres.

Les ajustements typiques piston-tube sont H8\/f7 ou H9\/g8, offrant un jeu optimal pour le fonctionnement des joints.<\/p>\n<p><strong>Les fonds et presse-\u00e9toupes<\/strong> assurent l&rsquo;\u00e9tanch\u00e9it\u00e9 du v\u00e9rin et le guidage de la tige. Le fond avant (presse-\u00e9toupe) contient les joints de tige, le racleur et la bague de guidage.
