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. Space Efficiency: Vertical design minimizes footprint in crowded facilities.
2. Global Voltage Flexibility:Ready for 220V/380V/460V power grids.
3. High-Pressure Stability: Engineered for consistent performance under heavy loads.
4. Integrated Valve System: Pre-assembled valves ensure precise flow/pressure control and leak-free operation.
5. Energy & Noise Reduction: Efficient pumps and compact layout lower power consumption and vibration.
6. Industrial Durability: Robust materials resist dust, moisture, and thermal stress.
7. Easy Maintenance:Accessible components simplify servicing.
8. OEM Custom Support:Tailored solutions for specific pressure, flow, and environmental needs.
