Furnace Grade Hydraulic Actuator

High-temperature hydraulic cylinders are specifically engineered for extreme thermal environments, utilizing advanced materials and innovative cooling technologies to maintain reliable operation. These specialized actuators feature multi-layer thermal protection systems including ceramic-coated piston rods, refractory metal alloy components, and phase-change cooling channels that actively regulate surface temperatures. The cylinders incorporate self-lubricating graphite composite bearings and metal-encased seals that withstand continuous operation at 300°C+ while preventing fluid vaporization. Their reinforced structures compensate for thermal expansion differentials, maintaining precise alignment under rapid temperature fluctuations common in industrial heating processes.     Critical applications include die-casting machine platens where the cylinders endure direct contact with 700°C molten metal while providing 2,000+ ton clamping force with 0.05mm parallelism.
