Preventive maintenance is a proactive maintenance strategy designed to prevent equipment failure before it occurs. This approach involves regular, scheduled inspections, servicing, and replacement of parts to ensure equipment operates efficiently and effectively. By adhering to a planned maintenance schedule, organizations can mitigate the risk of unexpected breakdowns, extend the life of their assets, and maintain operational continuity.

This approach stands out for its structured methodology, allowing maintenance teams to conduct tasks like lubrication, adjustments, and parts replacement at predetermined intervals based on manufacturers’ recommendations or historical data on equipment performance. The ultimate goal is to maintain machinery in peak operating condition, thereby enhancing reliability and reducing unplanned downtime.

While predictive maintenance also seeks to prevent failures, it relies on condition-monitoring data to determine when maintenance should occur, making it less scheduled than preventive maintenance. Reactive maintenance, on the other hand, is carried out after equipment has failed, leading to possible interruptions and increased costs. Corrective maintenance involves addressing specific issues, typically after a failure has been identified, rather than maintaining a schedule aimed at preventing such failures in the first place.
