7 - Bore treatment: Honing, skiving&roller burnishing

8 - Bore roughness control: Ra0.25um max or Ra0, 35um max for honed tubes, Ra0.25um max for skived&roller burnished tubes.

9 - End finish: Plain ends with square cuts, free of burrs for honed tubes.

Little bevelled ends for skived&roller burnished tubes.

10 - Standard export packing: In bundles tied with steel strips.

Int&ext oil coating.

End plastic caps.

External packing by PVC bags and knit bags.

11 - Customized packing and marking can be provided upon request.

12 - H8 tolerance: ID range Tolerance ID range Tolerance

18< d ≤30 +0/+0.033 180< d ≤250 +0/+0.072

30< d ≤50 +0/+0.039 250< d ≤300 +0/+0.081

50< d ≤80 +0/+0.046 300< d ≤315 +0/+0.081

80< d ≤120 +0/+0.054 315< d ≤400 +0/+0.089

120< d ≤180 +0/+0.063 400< d ≤500 +0/+0.097

13 - 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.
