product application

Application: hydraulic cylinder, pneumatic cylinder,Jack, cylinder barrel
Manufacture Method: cold drawn, cold rolled, Hot rolled+Deep Hole Boring 
Heat Treating Method/Delivery Condition:

BK	BKS	GBK	NBK	Q+T
+C	+SR	+A	+N	Q+T
Cold drawn	Stress relieved	Annealed	Normalized	QUENCHED + TEMPERED

Bore treatment: Honing, skiving&roller burnishing
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.
