Product Description
DIN 2391 ST52 Precision Seamless Steel Tube 120mm OD 20mm WT Cold Drawn Honed for Hydraulic Cylinder Barrel
DIN 2391 ST52 Cold Drawn Honed Seamless Precision Steel Tube for Hydraulic Cylinders
DIN 2391 ST52 (1.0580 / E355) cold drawn honed seamless precision steel tubes are the industry standard for hydraulic cylinder barrel manufacturing. With a precisely honed or skived-and-roller-burnished (SRB) inner surface, these tubes deliver the tight dimensional tolerances and surface finish required for reliable hydraulic piston seal performance.
Precision Manufacturing Process
- Cold Drawn Base Tube: Seamless ST52 steel tube cold drawn to achieve close OD/ID/wall thickness tolerances
- Skiving & Roller Burnishing (SRB): Advanced finishing process removes a thin layer (skiving) then cold-works the ID surface (burnishing) for Ra ≤0.2μm finish
- Honing Option: Conventional honing available for larger diameters with Ra ≤0.4μm surface finish
- High Strength Grade: ST52 provides excellent weldability and superior mechanical properties for demanding hydraulic applications
- Straightness Guaranteed: ≤1mm per meter ensures smooth piston travel without binding
