Product overviewThe ST52 ID Honed H8 hollow chrome-plated rod from EAST AI is a precision-engineered hydraulic rod manufactured from ST52 carbon steel. It combines internal-diameter honing (H8 tolerance) with a chrome-plated surface and a hollow structure to provide accurate fitment with seals and pistons, reduced weight and enhanced corrosion and abrasion resistance for industrial hydraulic and pneumatic systems.
Key features- Material: ST52 carbon steel for high tensile strength and wear resistance.
- ID honing: Precision internal-diameter honing for accurate ID dimensions and reduced internal friction.
- ID tolerance: H8 tolerance ensuring tight fit with pistons and sealing elements.
- Surface treatment: Chrome plated for improved corrosion and abrasion resistance.
- Structure: Hollow design to lower weight while preserving structural integrity.
- Straightness: ≤0.2/1000 mm.
- Roughness: ≤0.2 µm.
Applications- Hydraulic cylinders for mobile equipment and industrial machinery.
- Construction equipment (excavators, cranes, loaders).
- Agricultural machinery (tractors, harvesters, irrigation systems).
- Automotive manufacturing, lifting systems and other hydraulic/pneumatic systems requiring high strength and precision.
Packing & CustomizationAnti-rust oil is applied to the rod surface. Each rod is first wrapped in a protective paper roll and then packed in a wooden case. Custom packing, custom lengths and special machining or surface treatments are available on request.
