Product Description

Hydraulic Cylinder Seamless Steel 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. Honed tubes can be produced according to the demands of costumers that the degree of precision can reach H8/H9. Burnishing and honing service can be provided depending on the roughness requirement of inner diameter.
