Oem 140-180 Double Rack Swing Hydraulic Cylinder with Auto Leveling System

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 NOK, 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.

• Enhanced Torque: Dual racks deliver superior rotational force for heavy-load swinging.
• Auto-Leveling Precision: Maintains equipment stability on uneven terrain automatically.
• Synchronized Motion: Dual racks ensure smooth, balanced rotation without lag.
• Heavy-Duty Endurance: Hardened gears/rods withstand high-impact industrial cycles.
• Space Optimization: Compact design suits confined machinery layouts.
• Reduced Maintenance: Integrated sealing minimizes wear from dust/debris.
• OEM Integration: Custom mounts/controls ensure seamless compatibility and reliability.
