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 Resilience: Marine-grade materials and coatings resist saltwater corrosion, humidity, and UV exposure.
2. Heavy-Duty Performance: Engineered for high dynamic loads during container lifting/luffing in rough seas or port environments.
3. Precision Customization: Tailored stroke, force, mounts, and dimensions ensure seamless integration with unique equipment.
4. Safety & Stability: Synchronized movement prevents load sway, ensuring operational safety in offshore logistics.
5. Extended Lifespan:Hardened rods/seals minimize wear from abrasive coastal conditions.
6. Reduced Downtime:OEM reliability lowers maintenance frequency and operational disruptions.
7. Certification Compliance:Meets DNV/ABS/ISO standards for marine use. • The compact structure design and the use of high-strength materials ensure the extremely light weight of the cylinder
• The theoretical analysis and FEA calculation of the system ensure that the oil cylinder has a very high service life under heavy load
• Provide a variety of surface anti-corrosion treatment solutions: Ni/Cr plating, ceramic spraying, laser cladding, QPQ, etc.
• It can be designed and integrated according to requirements, including P.O. check valves, load holding valves, sequence valves,
relief valves, pressure measuring joints, etc.
• The design has a wide range of temperature resistance (-40℃～+100℃), and can provide higher or lower temperature cylinders
• Mature sealing system ensures that the cylinder has no jitter or crawling problems at low speeds
• The guide sleeve adopts a special anti-corrosion technology to ensure that the cylinder will work at a long time without rusting the guide sleeve
