👉 Idle fluid, also known as lubricating oil or grease, is a critical component in mechanical systems that facilitates smooth and efficient operation by reducing friction between moving parts. It is stored in reservoirs within the machinery and is released when needed to minimize wear and tear on components like bearings, gears, and pistons. This fluid not only lubricates but also helps dissipate heat, protect against corrosion, and maintain the integrity of seals and other components. Proper maintenance and timely replacement of idle fluid are essential to ensure optimal performance and longevity of mechanical systems.
