👉 A yield fluid, also known as a yield oil or yield grease, is a type of lubricant designed to provide long-lasting protection against wear and corrosion in mechanical systems. Unlike conventional lubricants that are primarily used for reducing friction, yield fluids have a high viscosity index and excellent stability, meaning they maintain their properties over a wide range of temperatures and resist breakdown. This makes them particularly effective in applications where the lubricant is subjected to extreme heat or cold, such as in engines, gearboxes, and industrial machinery. Yield fluids typically contain additives that enhance their performance, including anti-wear agents, extreme pressure additives, and antioxidants, ensuring prolonged service life and minimizing maintenance needs.
