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. Offshore Durability: Marine-grade materials/coatings resist saltwater corrosion, UV, and humidity.
2. High Dynamic Load Capacity: Engineered for heavy, shifting container stacks in rough seas.
3. Precision Synchronization:Ensures stable lifting/lowering even with vessel motion or uneven loads.
4. Leak-Proof Reliability:Critical in preventing hydraulic fluid spills in sensitive marine environments.
5. Custom Integration: OEM design matches exact mount points, stroke, and force requirements.
6. Extended Service Life:Hardened components reduce wear from abrasive coastal conditions.
7. Certified Safety:Complies with DNV/ABS standards for offshore operations. • The use of high-strength materials special heat treatment and welding processes ensure that the cylinder has a very high fatigue
life under high pressure and heavy load.
• Part of the cylinders are specifically designed to meet the harsh environmental conditions of the stacker and reclaimer
• Design a reliable sealing configuration for stackers and reclaimers for different types of cylinders
• It can be designed and integrated with P.O. check valves, counterbalance valves, etc. according to requirements
• The design has a wide range of temperature resistance (-30℃～+80℃), and can provide higher or lower temperature cylinders
• Working pressure, size specifications, installation methods, etc. can be customized according to the customer needs
