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. High Power Density:Optimized 80mm bore/56mm rod transfers 350+ bar pressure into maximum force with minimal energy loss.
2. Precision Engineering:ISO 6020-compliant machining ensures smooth operation (±0.05mm tolerance).
3. Leak-Free Reliability: Triple-sealing (rod/piston/buffer) prevents fluid loss at 250mm full stroke.
4. Reduced Friction:Hard-chromed rod + low-friction seals cut heat generation by 20%.
5. Extended Lifespan:Nitrided piston rods endure 500,000+ cycles in abrasive environments.
6. Custom Integration:Mounts/ports tailored to OEM machinery layouts.
7. Energy Efficiency: 95%+ volumetric efficiency reduces operating costs.

Application Scenarios :
Industrial Presses:Metal stamping/forging equipment requiring 250mm precise strokes under 250-ton loads.
Material Handling:High-cycle scissor lifts and conveyor pushers in logistics hubs (≥1,000 cycles/day).
Plastic Injection Molding:Ejection systems demanding micron-level repeatability (±0.1mm) at 200°C.
Steel Rolling Mills: Roll gap adjustment cylinders in high-heat (300°C+) environments.
Test Rigs:Fatigue testing machines needing 250mm stroke accuracy at 10 Hz frequency.
