Premium Quality Hydraulic Cylinders - Quality Assured

• 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 Japan , 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.

• Cost-Effective Simplicity: Single-port design reduces valve/hose costs by 40%.
• High Compression Force: 100mm bore delivers ≥15.7 tons thrust (at 200 bar).
• Long-Stroke Stability: 880mm stroke with anti-buckling guide sleeves (70mm rod).
• Low Maintenance: Spring/gravity retraction eliminates rod seal wear.
• Custom Protection: Hardened chrome rod + wiper seal for debris-prone environments.

• Industrial Presses: Scrap baling, powder compacting.
• Agricultural Machinery: Hay balers, silo compactors.
• Material Handling: Dock levelers, vertical lift gates.
• Construction: Pile driving, modular formwork.
• Recycling Plants: Cardboard/plastic compression rams.
• Railways: Coupler compression test rigs.
