Description
High-quality synthetic multigrade gear oil ROLF TRANSMISSION S7 AE 75W-90 is made on the basis of high-tech synthetic base oils, which provides a very high viscosity index, thanks to which the excellent low-temperature properties of the oil ensure a smooth gear shift at the lowest temperatures. The use of synthetic components also provides the oil with excellent thermal and oxidative stability, which guarantees the complete stability of the properties of the oil for the entire period of operation.
Application
ROLF TRANSMISSION S7 AE 75W-90 is designed for mechanical transmissions with all types of gears, including hypoid ones in cars and trucks and special equipment. It is used in heavily loaded gears, differentials, final drives, power take-offs, planetary gears operating at elevated temperatures, high speeds and impact loads, as well as low speeds and extremely high torques, in the design of which hypoid gears with large axle displacement are present where API GL-5 grade gear oils are required.
Key features
• Possesses excellent anti-seize properties, provides protection for friction pairs in heavily loaded nodes.
• Provides smooth gear shifting.
• Ensures stable properties over the entire application interval.
• The fluid has high heat capacity and stable viscosity at big difference of temperatures.
• Excellent low-temperature properties of the oil provide protection of transmission units at the time of cold start.
