Here below is the material data sheet of hydraulic cylinder tube.
CHARACTERISTICS OF OUR HYDRAULIC CYLINDER TUBE
High precision tolerances. Our honed hydraulic cylinder tube can meet ID tolerance of ISO 286-2 H7, H8, H9, … etc. upon customers’ request and its I.D dimension.
Seamless tube with high pressure resistance. We only use seamless cold drawn tubes to produce hydraulic cylinder tube, which means our honed cylinder tubing can work under higher pressure, thus our hydraulic cylinder honed tube is more reliable for hydraulic cylinder applications.
High Smooth inside surface; The roughness of our hydraulic cylinder tube is Max Ra 0.4 microns ID finish (16Max Ra ID Finish).
Flexible order quantity: we accept small quantity orders, even if there is only one piece of hydraulic cylinder tubing we can produce and supply.
Good weldability: The weldability of our hydraulic cylinder steel tube is very good, this is quite helpful for manufacturing the cylinders.
