👉 A rated fluid, often referred to as a lubricant or fluid film, is a substance used to reduce friction and wear between moving mechanical parts. It is typically characterized by its viscosity, which indicates its thickness or resistance to flow, and its ability to form a protective film between surfaces in relative motion. This film prevents direct contact between the surfaces, minimizing wear and heat generation, and ensuring smooth operation of machinery. Rated fluids are specifically formulated for various applications, such as automotive, aerospace, and industrial machinery, and come with performance ratings that specify their suitability for different operating conditions, temperatures, and loads. Common types include mineral oils, synthetic oils, greases, and silicone-based fluids, each offering distinct properties tailored to specific needs.
