Question: 1 / 400

What does "lubrication" prevent in machinery?

Overheating from high speed

Wear and tear from friction

Lubrication plays a critical role in machinery by forming a protective film between moving parts. This film significantly reduces friction, which is a major contributor to wear and tear in mechanical components. When two surfaces slide against each other without sufficient lubrication, they can generate heat and lead to metal fatigue or surface damage over time.

By applying the right lubricant, it not only minimizes friction but also helps to dissipate heat, ensuring that machinery operates smoothly and efficiently. This ultimately extends the lifespan of components and enhances overall performance. Other factors, like overheating from high speeds or dirt accumulation, do impact machinery, but lubrication specifically targets the prevention of wear caused by friction, making it crucial for maintaining optimal functionality.
