II. Key Features

  • Hardened Surface

    Utilizing professional induction heat treatment, the surface hardness is stabilized at HRC 55-63. This provides exceptional wear resistance in extreme friction environments, significantly extending the full lifecycle of the hydraulic cylinder.

  • High Precision

    Strictly compliant with f7 tolerance and Ra 0.2-0.4 roughness standards. This ensures a perfect fit with seals, minimizing frictional resistance and effectively preventing system leakage.

  • Superior Corrosion Resistance

    The dense chrome layer formed by precision electroplating creates a durable antioxidant barrier against acidic mine water or marine salt spray, protecting the internal steel core.


III. Applications

  • Mining Machinery: Boom cylinders for large excavators, deep-well hydraulic supports, and mining harvesters.

  • Energy & Power: Offshore oilfield compensation systems, wind turbine hydraulic adjustments.

  • Construction Machinery: Crane hydraulic systems, pile drivers, and tunnel boring machine (TBM) components.

  • Automotive & Automation: High-performance engine piston components, precision transmissions for industrial robots.

V. International Export Packaging

Individual Protection: Each piston rod is equipped with an independent protective sleeve to prevent surface scratching during transit.

Dual-Layer Anti-Rust: Surfaces are coated with specialized anti-rust oil and hermetically sealed with vacuum-grade moisture-proof film.

Heavy-Duty Shipping: Packed in reinforced export-grade fumigated wooden cases with internal anti-shock supports to ensure "Zero Damage" during transoceanic shipping.
