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.
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.
