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 perio processes.
3. **Thermal Stability:** Resists deformation at 150°C+ ambient temperatures.
4. **Custom Integration:** Tailored porting, flow, and valve logic match OEM machine layouts.
5. **Leak-Free Reliability:** Reduces hydraulic oil consumption and contamination risks.
6. **Low Maintenance:** Hardened spools/seals withstand abrasive metal particulates.
7. **Energy Efficiency:** Optimized flow paths cut power losses by 15–25%.

### **Application Scenarios (50 words):**
- **Machine Tools:**
Precision spindle clamping, tool changer sequencing, and feed axis control in CNC mills/lathes requiring ±0.01mm repeatability.
- **Metallurgy:**
Hydraulic systems for continuous casting mold oscillation, rolling mill gauge control, and forging press automation in high-heat (300°C), high-shock steel plants. Ensures process stability under extreme loads.
1. Precision Control:Enables micron-level positioning accuracy for machining/metallurgical processes.
2. High-Pressure Resilience: Sustains 350+ bar pressures in forging/rolling operations.
