EAXLE (Electric Drive Axle) systems represent the core propulsion technology in modern electric vehicles (EVs), integrating motors, gearboxes, and power electronics into a single compact unit. Unlike traditional drivetrains, EAXLEs operate under extreme thermal and electrical stresses, demanding specialized lubrication solutions. This is where IDEMITSU EAXLE FLUID TYPE-A emerges as an engineering breakthrough—a fluid specifically formulated for the unique challenges of next-generation EV powertrains.
Engineered to withstand temperatures exceeding 150°C while maintaining viscosity integrity, TYPE-A prevents thermal runaway in high-RPM EAXLE environments. Its synthetic base oils resist oxidation, ensuring consistent performance across -40°C to 200°C operational ranges—critical for battery thermal management integration.
With a dielectric strength >35 kV/mm, TYPE-A creates an insulating barrier between high-voltage components (e.g., 800V architectures), preventing arcing and short circuits—a non-negotiable safety feature absent in conventional gear oils.
Patented anti-wear additives form sacrificial films on gears and bearings, reducing metal-to-metal contact by 62% (ASTM D4172 tests). This extends EAXLE service intervals to 240,000 km while mitigating NVH (Noise, Vibration, Harshness) issues common in high-torque EV applications.
Validated for seamlessFKM/FFKM), and rare-earth magnets—preventing corrosion and swelling that could compromise motor efficiency.
