👉 A contact fluid, often referred to as a lubricant or grease, is a substance applied between two surfaces that come into direct contact to reduce friction and wear. It forms a thin, protective layer that minimizes metal-to-metal contact, thereby enhancing the efficiency and longevity of mechanical components. These fluids can be mineral-based, synthetic, or even bio-based, each tailored for specific applications such as automotive, industrial machinery, or aerospace. Contact fluids come in various forms, including liquids, greases, and solid pastes, each designed to meet particular environmental and operational requirements. By effectively managing heat and preventing corrosion, contact fluids play a crucial role in maintaining the optimal performance of machinery and equipment.
