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).
