Oem Industrial Machinery Hydraulic Cylinders 150 100-380 Series

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 period.

Advantages :
1. Heavy-Duty Force:150mm bore/100mm rod delivers 500–1,000 kN thrust at 350 bar.
2. Extended Stroke: 380mm travel enables deep-reach operations.
3. Precision Tolerance:ISO 6020 compliance ensures ±0.05mm machining accuracy.
4. Abrasion Resistance: Hard-chromed rods + PTFE seals withstand gritty industrial environments.
5. Leak-Free Design:Multi-stage sealing prevents fluid loss.
6. Thermal Stability: Operates reliably in -30°C to 200°C ranges.
7. Custom Integration:Ports/mounts tailored to OEM layouts.

Application Scenarios :
Metal Processing: Press brake bending cylinders (≤380mm stroke) and rolling mill gap control under 800°C ambient heat.
Heavy Lifting:Scissor lift platforms in logistics centers requiring 30-ton capacity.
Mining Equipment: Ore crusher pushers and conveyor tensioners in high-dust/impact conditions.
Rubber Molding:Vulcanizing press ejection systems demanding micron-level precision.
