Hydraulic Cylinder Barrel | Pneumatic Cylinder Barrel

Product Details Overview

Cylinder barrel is the main part of the cylinder body, the main fuction of cylinder barrel is to contain cylinder pressure. Hydraulic cylinder barrel is the cylinder barrel for hydraulic cylinder, it is known as hydraulic cylinder tubes also. And the cylinder barrels for penumatic cylinders are known as penumatic cylinder barrel. 

As one of the leading hydraulic cylinder barrel manufacturers & suppliers, our factory produces full size range of hydraulic cylinder barrels with various steel grades. This is one of our main products.

Advantages of Skyline’s Cylinder Barrel

• High precision tolerances;
  Our cylinder barrel can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension.
• Seamless tube with high pressure resistance;
  We only use seamless cold drawn tubes to produce the cylinder barrel, which means our hydraulic cylinder barrel can work under higher pressure, thus our hydraulic cylinder barrels are more reliable for hydraulic cylinder applications.
• High Smooth inside surface;
  The roughness of the inner diameter of our cylinder barrel is Max Ra 0.4 microns ID finish (16Max Ra ID Finish). Honing process and Skiving & Roller burnishing (SRB) process are the two main types of processes for manufacturing cylinder barrels, with the above process, the inner surface is super smooth.
• Flexible order quantity: we accept small quantity orders, even if there is only one piece of hydraulic cylinder barrel or penumatic cylinder barrel, we can also produce and supply.
• Good weldability: The weldability of our cylinder barrel is very good, this is quite helpful for manufacturing the cylinders.
