What can happen if lubricants are not replaced in a timely manner?

When lubricants are not replaced in a timely manner, the most significant consequence is the increased risk of contamination and wear. Over time, lubricants can break down due to oxidative degradation, thermal breakdown, and contamination from dirt, metal debris, or moisture. This degradation reduces the lubricant's effectiveness and can lead to less protection for moving parts within machinery.

As the lubricant loses its ability to effectively reduce friction and remove heat, it may result in increased wear on components. The lubricating film may thin, allowing metal surfaces to come into contact with each other, leading to premature failure of parts. Additionally, contaminants can exacerbate wear by introducing abrasive particles into the lubrication system. Therefore, timely lubricant replacement is critical to maintaining equipment health and ensuring optimal performance.
