Premium Quality Hydraulic Cylinders - Quality Assured

1. Internals:Cylinder barrel adopts GUOYUE EU/US metallurgical standard CD250 structure. Barrel material: 45#, 42CrMo, or 27SiMn. Bore honed to H8 precision with surface roughness Ra<0.4μm. Heads, base, trunnions, and pistons are exclusively made of 45# steel; no cast iron or cast steel components are used.
2. Buffering:Multiple buffering options including fixed and floating buffer structures to ensure effective deceleration across various pressures and speed ranges.
3. Welding:100% ultrasonic impact treatment applied to all pressure-bearing and load-critical welds. This eliminates weld stress (removal rate ≥90%) and significantly enhances weld fatigue strength.
4. Sealing:All cylinders exclusively use premium imported seals from Japan NOK, Sweden Trelleborg, Germany Merkel, and GP. No domestic seals are utilized.
5. Testing &Certification:Factory testing strictly complies with GB/T15622-2005 "Hydraulic Fluid Power - Test Methods for Cylinders" and internal premium standard Q/GAKY014-2023. Includes provision of factory test reports and product qualification certificates.
6. Warranty: One-year warranty from shipment date. Free repair or replacement provided for defects arising from design or manufacturing within the warranty period. Advantages:1. Extreme Environment Resilience:Marine-grade materials resist saltwater corrosion, humidity, and harsh offshore conditions.
2. Precision Customization:Tailored dimensions, stroke, force, and mounting ensure perfect integration with unique Ro-Ro systems.
3. High Load Reliability:Engineered for heavy-duty latching/securing under dynamic loads and vessel motion.
4. Safety-Critical Design:Fail-safe mechanisms prevent accidental release, ensuring platform/structure stability.
5. Minimal Maintenance: Sealed construction and hardened surfaces withstand abrasive marine environments.
6. Direct OEM Value:Optimized performance, reduced downtime, and lifecycle cost savings versus adapted solutions.
7. Certification Compliance:Built to meet offshore/marine standards (e.g., DNV/ABS).
