Overview of Hydraulic Cylinder Tubes

Product Name: Hydraulic Cylinder Tube

Suitable for (1) Ready to use (H9), (2) Skiving, Roller Burnishing & Honing (HPZ), (3) Chrome Plating

A hydraulic cylinder tube is a precision-made hollow cylinder, typically constructed from steel or other high-strength materials (E355), and designed for use in hydraulic systems. It is usually made of cold drawn welded tubes (DOM). Hydraulic cylinder tubes are usually used to produce hydraulic cylinder body, so it is called hydraulic cylinder barrel. H9 tubing is primarily used to improve the geometric form of a surface and the surface texture.

Advantages of Hydraulic Cylinder Tube

High precision tolerances, as per EN10305-2 / Client requirement
Smooth inside surface for H9 – The ID roughness requirement is Max Ra 0.8, we can maintain the same well within 0.4 Ra max, or as per client requirement.
Flexible order quantity: we accept small quantity orders, even if there is only ten piece of hydraulic cylinder tubing we can produce and supply.
Good weld-ability: The weld-ability of these tubing is very good, this is quite helpful for manufacturing the cylinders.

Main Applications of Hydraulic Cylinder Tubing

These tubing are mostly used as cylinder tube, such as hydraulic cylinder tube, which are widely used for manufacturing and repairing hydraulic cylinders. As H9 tube usually has very high dimension tolerance and good surface smoothness, so this product is also used in applications where precision dimension or high smooth surface is need. For examples, H9 tubes are suitable for various kinds of Precision Mechanical Tube, Cylinder Tubing and Hydraulic Cylinder, Construct use Multi Joint Tube, Steel Axis Pipe, Injection Machine and Robotic Arm, and so on.

Product Standard

H9 hydraulic cylinder tube is usually produced according to norms as EN10305-2, ASTM A513, etc on customer’s request.

Size Range

We manufacture honed tubes in metric dimensions size range from O.D 50 mm to O.D 200 mm, Wall thickness 3.0 – 14.0 mm

Carbon Steel Hydraulic Cylinder Tubing is available with grades as below

E355 Other steel grades of H9 tube is available on customer’s request.

Below is the chemical composition & mechanical properties of the main steel grades for honed cylinder tube.

Grade	Chemistry	%	Yield	Tensile	Elongation	Typical Hardness
