👉 Gear fluid, also known as gear oil or transmission fluid, is a specialized lubricant designed specifically for use in gearboxes and other mechanical systems where gears are the primary mode of power transmission. It serves multiple critical functions: reducing friction between moving gear teeth to minimize wear and heat generation, dissipating heat produced during operation, and providing protection against contaminants such as dirt, dust, and moisture that could otherwise degrade gear performance or cause damage. Gear fluid also helps in maintaining the proper lubrication film thickness, ensuring smooth and efficient operation while extending the lifespan of the gear components. Its formulation is carefully engineered to meet the unique demands of high-speed, high-load applications found in gearboxes.
