Product Introduction
Oil Film Bearing Oil is a specialized high-performance lubricant designed for foil bearing systems. Formulated with advanced synthetic base oil and foil bearing-specific additives, it complies with ISO 6743-9 standards and delivers exceptional lubrication for high-speed foil bearings.
This product is compatible with industrial bearing oil and bearing circulating oil applications, engineered to meet the unique requirements of foil bearing systems in high-speed rotating equipment.
It provides excellent high-temperature stability, low friction, and anti-wear performance, ensuring reliable operation of foil bearings at high speeds while extending service life.
Oil film bearing oil is the ideal choice for foil bearings in turbines, compressors, and high-speed motors.

Material & Product Details
• Core Material: Advanced synthetic base oil (PAO blend) blended with foil bearing-specific anti-wear additives, oxidation inhibitors, and friction modifiers. The oil has excellent high-temperature stability and low viscosity at operating temperatures, with mechanical impurity content ≤0.002% to meet foil bearing requirements.
• Product Details: ① High-Temperature Stability: Maintains performance at temperatures up to 180℃, suitable for high-speed foil bearing operation; ② Low Friction: Low viscosity at operating temperatures reduces friction and energy consumption, improving bearing efficiency; ③ Anti-Wear Protection: Enhanced anti-wear additives protect foil bearing surfaces from abrasive wear, extending service life; ④ Thermal Oxidation Resistance: Resists degradation and sludge formation at high temperatures, extending oil change intervals; ⑤ Compatibility: Formulated to be compatible with foil bearing materials, including aluminum, steel, and polymer composites.
