1.Hydraulic cylinder tube

The hydraulic cylinder tube is the main part of the hydraulic cylinder.The inner 
hole of the hydraulic cylinder tube usually precision processed by boring,reaming,rolling 

or honing.By these process can ensure the piston,sealing elements and the support 
elements move smoothly,then ensure the sealing effect and reduce the abrasion.The 
hydraulic cylinder tube will bear big pressure,so need high strength and stiffness.


2.Hydraulic Tube Material
JIS STKM13C, DIN ST52, SAE1020 or Mechanical Construction Use Carbon Steel Pipes, Other Specifications Can be made Customer Request based on.
