👉 A float fluid, also known as lubricating oil or hydraulic fluid, is a substance that reduces friction between moving parts in mechanical systems, such as engines, gears, and bearings. It is typically a viscous liquid or gel-like material that flows easily under pressure but resists flow at rest. This fluid is crucial for ensuring smooth operation, minimizing wear and tear, and maintaining the efficiency of machinery. By providing a thin layer of protection between surfaces, float fluids help prevent damage and prolong the lifespan of mechanical components.
