Klübersynth GE 4 75 W 90 is a fully synthetic gear oil based on polyα-olefins, offering high shear stability and protection under impact loads, making it particularly suitable for heavily loaded rail vehicles.

Klübersynth GE 4 75 W 90 meets the API GL-5 synthetic grease anti-seize load requirements. Thus, it is suitable for gears that require API GL-4 or API GL-5 performance levels. This product offers excellent wear protection for gears and rolling bearings, ensuring the long-lasting life of lubricating components. According to the FVA 54/7 standard, it can achieve a micro-pitting resistance grade of GFT≥10, providing sufficient protection for gears under high loads or those typically prone to such damage.

Synthetic base oils exhibit excellent shear resistance, preventing the lubricating oil film from thinning even under high-load conditions. Due to their anti-oxidation and anti-aging stability, their service life is significantly longer than that of mineral oils, thereby extending the maintenance cycle.

Excellent low-temperature performance ensures reliable operation of gear components even at very low temperatures. Good anti-foaming and anti-corrosion properties enhance the operational stability of lubricated parts.
