Product Description
Mobil™ Synthetic HSR Gear Oil 75W-80 is a fully synthetic, high performance gear lubricant formulated from advanced synthetic base oils and the latest technology additive system. This lubricant is engineered for use in many railway gearboxes, especially high speed rail transmission gearboxes where operations require gear lubricants with exceptional thermal stability and resistance to high temperature oxidation, excellent load-carrying capability over wide operating temperatures where extreme pressures and shock loading are expected and long oil drain interval. Mobil™ Synthetic HSR Gear Oil 75W-80 has excellent thermal and oxidation stability, high inherent Viscosity Index (VI), extremely low pour point, and outstanding low temperature fluidity.
The state-of-the-art technology behind Mobil™Synthetic HSR Gear Oil 75W-80 delivers outstanding viscosity-temperature properties necessary for wide temperature range applications, optimized protection against thermal degradation and oxidation, wear and corrosion, shear stability, extended service capability, and potential energy saving.
