What is the main purpose of lubrication in machinery?

The main purpose of lubrication in machinery is to reduce wear between moving parts. When mechanical components move against each other, friction is generated, which can lead to wear and tear over time. Lubrication forms a protective film between these surfaces, significantly minimizing direct contact and, consequently, reducing friction. This allows for smoother movement, decreases the heat generated by friction, and extends the lifespan of machinery components by preventing premature wear.

While cooling components is a potential benefit of lubrication, as it can help dissipate heat generated during operation, the primary function of lubrication is focused on wear reduction. The prevention of electrical conductivity is relevant in certain contexts but is not a fundamental purpose in general machinery lubrication. Increasing friction is contrary to the intended function of lubrication and undermines its role in keeping machinery operating efficiently.
