Product Description
1.Hydraulic Cylinder TubeUsed in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 and 1020. We can work and get the mechanical property of the clients need and extended the life of the hydraulic cylinder.
2. Honed tube ----- used in Elevator buffer and Hydraulic Cylinder. This kind tube have a better roughness inner the tube, ra0.2-0.4um and can use directly in the hydraulic cylinder tube. Range: ID 50-250mm and Length can work at most 6M.
3. Cold finished tube---- Widely Used. Processing range 30-300mm, biggest length is 11M.

Bore roughness control: Ra0.25um max or Ra0, 35um max for honed tubes, Ra0.25um max for skived&roller burnished tubes.
End finish: Plain ends with square cuts, free of burrs for honed tubes. Little bevelled ends for skived&roller burnished tubes.
Difference between honed tube and skived&roller burnished tube: In hydraulic cylinder industry, there are 2 solutions for bore treatment: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing leads to different internal surface image, but both ensure good roughness.
Standard export packing: In bundles tied with steel strips. Int&ext oil coating. End plastic caps. External packing by PVC bags and knit bags.
Customized packing and marking can be provided upon request.
1. Bundle and pack.
