Key Features and Advantages
Superior Surface Characteristics: Through advanced manufacturing techniques including skiving, roller burnishing, and honing processes, our hydraulic cylinder tube products achieve exceptional internal surface finishes with roughness values typically ranging between Ra 0.2-0.4μm . This optimized surface topography significantly reduces friction between the tube interior and piston seals, minimizing wear while enhancing operational efficiency and service life.
Enhanced Mechanical Properties: The manufacturing process induces beneficial cold work effects that increase surface hardness typically by HV≥4° and improve overall fatigue strength by up to 30% . These enhanced mechanical properties directly contribute to the tube's ability to withstand pressure fluctuations and cyclic loading conditions encountered in demanding hydraulic applications.
Precision Dimensional Control: Our hydraulic cylinder tube products are manufactured to exacting dimensional tolerances, with standard internal diameter precision reaching ISO H7, H8, or H9 classifications . This precision ensures optimal compatibility with piston assemblies and seal components, reducing break-in periods and preventing premature seal failure.
Material Excellence: We utilize premium materials including SAE1020, ST52, SAE1045, 4140 alloy steel, and various stainless steel grades to meet different application requirements . Each material is selected based on its specific mechanical properties and suitability for particular operating environments, ensuring optimal performance characteristics.
Structural Integrity: Our manufacturing process ensures excellent straightness (typically ≤0.5/1000mm) and roundness characteristics , which are critical for proper seal function and overall cylinder performance. This dimensional stability is maintained throughout the tube's service life, even under substantial operating pressures.
Types of Hydraulic Cylinder Tubes
Cold Drawn Honed Tubes: This category represents the standard for general hydraulic applications, combining cold drawing processes with precision honing to achieve superior dimensional accuracy and surface finish. These tubes offer an excellent balance of performance characteristics and cost-effectiveness for a wide range of industrial applications.
Skived and Roller Burnished Tubes: For high-performance applications requiring exceptional surface characteristics, this manufacturing approach combines skiving (a precision cutting operation) with roller burnishing to create an optimized internal surface with superior finish qualities and enhanced pressure-bearing capabilities.
Seamless Precision Tubes: Manufactured without welded seams, these tubes provide uniform strength characteristics throughout their circumference, making them ideally suited for high-pressure applications where reliability is paramount. The seamless construction eliminates potential failure points associated with welded tubes.
Stainless Steel Hydraulic Tubes: Specifically engineered for applications requiring enhanced corrosion resistance, these tubes utilize stainless steel compositions to withstand aggressive environments while maintaining the necessary mechanical properties for hydraulic applications . They are particularly valuable in marine, chemical processing, and food industry applications.
Custom-Engineered Solutions: Beyond our standard product lines, we develop application-specific hydraulic cylinder tube solutions tailored to unique operational requirements, including specialized dimensions, material compositions, or performance characteristics not covered by standard offerings.
