The practice that involves inspecting and replacing worn parts before they fail is known as preventive maintenance. This approach is designed to decrease the likelihood of equipment failure and extend the lifespan of machinery by regularly scheduled maintenance activities. By addressing wear and tear proactively, maintenance technicians can minimize downtime and optimize equipment performance.

Preventive maintenance may include routine checks, lubricant applications, part replacements, and other tasks carried out on a planned schedule, regardless of whether the equipment appears to be malfunctioning. This is distinctly different from reactive maintenance, which only occurs after a failure has happened, and from corrective maintenance, which is focused on remedying problems after they arise. Predictive maintenance, on the other hand, uses data analysis and monitoring techniques to predict when maintenance should be performed based on the actual condition of the equipment, rather than a set schedule. This makes preventive maintenance crucial in establishing a structured approach to maintain equipment reliability and efficiency.
