High Load Hydraulic Cylinder for Excavators 16MPa 127mm

• Internals: Cylinder barrel meets GUOYUE EU/US metallurgical standard CD250 structure with materials including 45#, 42CrMo, or 27SiMn. Bore honed to H8 precision with surface roughness Ra<0.4μm.
• Buffering: Multiple buffering options including fixed and floating buffer structures for effective deceleration across various pressures and speed ranges.
• Welding: 100% ultrasonic impact treatment on all pressure-bearing welds, eliminating weld stress (≥90% removal rate) and enhancing fatigue strength.
• Sealing: Exclusively uses premium imported seals from Japan NOK, Sweden Trelleborg, Germany Merkel, and GP.
• Testing & Certification: Complies with GB/T15622-2005 and internal premium standard Q/GAKY014-2023, including factory test reports and product qualification certificates.
• Warranty: One-year warranty from shipment date with free repair or replacement for defects arising from design or manufacturing.

Designed for extreme durability, this high-load hydraulic cylinder delivers powerful lifting/digging force with corrosion resistance and long service life under heavy stress. Its sealed design prevents contamination while precision engineering ensures smooth operation in harsh conditions like mining, construction, and earthmoving with minimal maintenance.

Essential for excavators, mining shovels, crawler cranes, and demolition equipment. Used in trench digging, rock breaking, and heavy material handling. Ideal for off-road construction, quarrying, and disaster recovery where high torque, impact resistance, and reliability in muddy/dusty environments are critical.
