  ST52 Honed barrel   is also called Honed tube.   Cylinder barrel   is the main body of   hydraulic cylinder , and its inside hole is commonly manufactured by use of boring, reaming, rolling and honing and other precision machining processes to enable the piston and seals and bearing to slide smoothly, thereby ensuring the sealing effect and reducing wear and tear; The cylinder barrel bear a lot of hydraulic pressure, and therefore, it should have sufficient strength and rigidity.

  The Advantages Of Our Honed Bore Cylinder Tube Honed bore cylinder tube is a kind of smooth bore steel tube used to manufacture hydraulic cylinder barrels that is the core part of a piece of hydraulic cylinder .Honing is a kind of machining technology. Through honing head, the inner hole of cold drawn seamless tube is processed by reciprocating high-speed grinding technology, so that the inner hole can meet the requirements of tolerance size and surface roughness that we need. Advantages of Our Hone Bore Cylinder Tube 1.High precision tolerances; Our honed tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension. 2.Seamless tube with high pressure resistance;We only use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications. 3.High Smooth inside surface; The roughness of our honed pipe is Max Ra
