Advantages of Our 4140 hydraulic cylinder barrel
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 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.
