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 Efficiency & Power Density: Piston pumps (especially A4V, A10V variable types) offer superior volumetric efficiency and handle very high pressures in compact designs.
Variable Flow & Control: Models like A4V, A7V, A10V provide precise, efficient variable displacement for optimized system control and energy savings.
2.Robustness & Reliability:Gear pumps offer simple, cost-effective, robust operation for medium-pressure applications.
3.Application-Specific Optimization:OEM customization tailors performance, mounting, ports, and controls precisely to your hydraulic system's demands, enhancing longevity and integration.
4.Proven Technology:Utilizing established, reliable hydraulic pump designs ensures dependability
