Premium Quality Hydraulic Cylinders
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.
Buffering: Multiple buffering options including fixed and floating buffer structures to ensure effective deceleration across various pressures and speed ranges.
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.
Sealing: All cylinders exclusively use premium imported seals from Sweden Trelleborg, Germany Merkel, and GP. No domestic seals are utilized.
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.
Warranty: One-year warranty from shipment date. Free repair or replacement provided for defects arising from design or manufacturing within the warranty period.
Key Advantages
Robust Construction: Engineered to withstand extreme thrust forces, ground pressure, and shock loads in challenging geological conditions.
Precision Alignment: Ensures accurate tunnel boring and segment placement, critical for tunnel integrity.
Extended Lifespan: High-grade materials and hardened surfaces resist abrasive wear and corrosion.
Optimized Performance: Custom OEM design ensures perfect fit, seamless integration, and reliable operation with specific TBM models.
Enhanced Stability: Maintains shield alignment and stability during excavation and ring building.
Cost Efficiency: OEM sourcing reduces long-term maintenance and replacement costs.
Geological Adaptability: Designed to handle variable ground conditions reliably.
