Oem China Quality Supplier's Hydraulic Piston Cylinder 50 35-200 Series Premium Hydraulic Cylinders

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. Precision Engineering: Strict ISO 6020/6022 compliance ensures dimensional accuracy (50mm bore/35mm rod).
2. High-Pressure Endurance:Reinforced seals & hardened rods sustain 350+ bar operations.
3. Extended Durability:500,000+ cycles under abrasive/dusty conditions.
4. Leak-Free Guarantee: Triple-sealing (rod/buffer/wiper) prevents fluid loss.
5. Custom Integration:Stroke (≤200mm), mounts, ports tailored to OEM layouts.
6. Corrosion Defense:Electroplated rods + phosphate coatings.
7. Cost Efficiency:Premium quality at 20–30% lower cost than EU/US brands.

Application Scenarios :
Industrial Automation:Precision pressing/stamping in automotive part production lines (±0.1mm repeatability).
Material Handling: Scissor lifts, conveyor pushers, and palletizing robots requiring 200mm stroke reliability.
Agricultural Machinery:Tractor implements (e.g., plow depth control) resisting mud/chemical corrosion.
Steel Plants: Roll gap adjustment cylinders in rolling mills enduring 300°C ambient heat.
