Lubrication is the process of applying a substance, often called a lubricant, to reduce friction between surfaces in mutual contact. This helps to minimize wear and tear, enhance efficiency, and prevent overheating in machines and mechanical systems. Common lubricants include oils, greases, and even water, depending on the application. In various industries, such as automotive and manufacturing, proper lubrication is essential for maintaining equipment performance and longevity. For example, in a car engine, oil lubricates moving parts, allowing them to operate smoothly. Regular maintenance and lubrication can significantly extend the lifespan of machinery and reduce the risk of breakdowns.
