Gear oil is primarily composed of petroleum-based lubricating base oil or synthetic lubricating oil. Gear oil mainly refers to the lubricating oil used in transmissions and rear axles. There are differences between gear oil and engine oil in terms of usage conditions, composition, and performance characteristics. Gear oil primarily functions to lubricate gears and bearings, prevent wear and rust, and assist in heat dissipation for gears. Automotive gear oil is used in gear transmission mechanisms such as automotive steering gears, transmissions, and drive axles. Due to the high surface pressure during gear transmission, gear oil plays a crucial role in lubrication, anti-wear, cooling, heat dissipation, anti-corrosion and anti-rust, cleaning, and reducing gear surface impact and noise.
