Oem Hydraulic Cylinder Single Action 140 100-6550 Hydraulic Cylinder
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.
Advantages
This OEM single-action hydraulic cylinder (140mm bore, 100-6550mm stroke) delivers high thrust force with minimal maintenance. Features robust carbon steel construction, precise machining tolerances, and long-stroke stability. Integrated buffering prevents end-impact damage, while hard-chromed rod ensures corrosion resistance for extended service life in demanding conditions.
Applications
Essential for foundry equipment, steel mill pushers, and heavy-duty presses. Used in shipyard launching systems, dam gate actuators, and mining machinery. Ideal for long-stroke industrial applications requiring linear force in metal processing, civil engineering, and material handling where reliability outweighs return-stroke complexity.
