Customized Telescopic Hydraulic Cylinder 125 70-2500 Long Stroke Hydraulic Cylinder Single Acting Hydraulic Cylinder Price

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 Key Advantages:
Space Efficiency: Multi-stage design achieves 2.5m stroke while collapsing to ≈30% length.
High Vertical Force: 125mm bore generates ≥15t thrust (at 200 bar).
Simplified System: Single-acting cuts hose/valve costs.
Custom Durability: Hard-chromed rods + wear-resistant seals (e.g., Viton) suit harsh environments.
Precision Control: Guided stages prevent buckling under heavy asymmetric loads.

Critical Applications :
1. Dump Trucks/Tippers: Multi-stage lifting for coal/ore transport.
2. Mobile Cranes: Boom extension in confined spaces.
3. Waste Compactors: High-stroke compaction rams.
4. Agricultural Hoists: Silo unloaders, grain trailer lifts.
5. Industrial Lifts: Vertical platform elevators (e.g., warehouse scissor lifts).
6. Marine Equipment: Ship hatch covers, dock levellers.
