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.Extreme Torque Density: Delivers massive starting & low-speed torque essential for demanding rotary drilling applications in a compact bent-axis design.
2.Superior Power & Speed Control:Precise variable displacement enables optimal drilling speed/power adaptation for varying soil/rock conditions, maximizing efficiency.
3.Robust Construction:Engineered to withstand extreme shock loads, high continuous pressure, and harsh drilling site environments (dust, vibration, moisture).
4.High Efficiency:Advanced piston/port plate design minimizes energy loss, reducing heat buildup and fuel consumption.
5.Reliable Contamination Resistance:Enhanced sealing and filtration tolerance ensure longevity despite inevitable hydraulic fluid contamination.
6.Optimized Integration:Custom OEM design ensures perfect mounting, shaft interface, porting, and control integration for the specific rig.
