High Temperature Hydraulic Cylinder 25MPa 30mm Stroke

• 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.

This high-temperature resistant hydraulic cylinder ensures reliable performance in extreme heat (up to 300°C+). Features double-stroke precision, heat-resistant seals, and robust alloy construction to prevent deformation. Corrosion-resistant coatings enhance durability, while smooth operation minimizes wear. Ideal for demanding environments requiring consistent power and thermal stability.

Used in steel mills, foundries, glass manufacturing, and ceramic kilns where extreme heat is present. Also applied in industrial furnaces, plastic molding machines, and aerospace testing equipment. Suitable for automotive forging presses and heavy machinery operating in high-temperature conditions, ensuring longevity and efficiency under thermal stress.
