Stainless Steel Cylinder Tubes
TECHNICAL DATA SHEET (TDS)
Stainless Steel Cylinder Tubes (Honed / Skived & Roller Burnished)
1. Product Description
Stainless steel cylinder tubes are precision-engineered components designed for hydraulic and pneumatic cylinder applications. The tubes are internally machined by honing or skiving & roller burnishing to achieve tight dimensional tolerances and low surface roughness, ensuring optimal sealing performance and reduced friction during operation.
These tubes are suitable for high-pressure environments and corrosive service conditions where both mechanical performance and corrosion resistance are critical.
2. Manufacturing Process
●Raw Material: Seamless stainless steel tubes (hot finished or cold drawn)
●Heat Treatment: Solution Annealing / Stress Relieving
●Internal Machining: Honing or Skiving & Roller Burnishing
●Straightening: Multi-roll precision straightening
●Final Inspection: 100% dimensional and surface quality verification
