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 Torque Density:Generates exceptional starting and low-speed torque in a compact, space-saving bent-axis design, crucial for track drive power.
2.Robustness & Reliability: Proven heavy-duty construction withstands extreme shock loads, pressure peaks, and harsh environments typical in crane applications.
3.High Efficiency: Delivers excellent mechanical and volumetric efficiency, maximizing power transfer and reducing heat generation.
4.Low Speed Stability: Operates smoothly and controllably at very low speeds without crawling.
5.Custom Integration:OEM tailoring optimizes mounting, shaft, ports, and controls for seamless, reliable integration into the crane's drive system.
6.Long Service Life:Durable design and materials ensure extended operational life with minimal maintenance.
