Hydraulic cylinder tube

1.The hydraulic cylinder tube is the main part of the hydraulic cylinder.

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

or honing.

3.By these process can ensure the piston,sealing elements and the supportelements move smoothly,

then ensure the sealing effect and reduce the abrasion.

4.The hydraulic cylinder tube will bear big pressure,so need high strength and stiffness.
