What type of maintenance involves replacing parts based on a schedule?

Preventive maintenance is a strategy designed to ensure equipment operates efficiently and to prevent unexpected failures by replacing parts and performing routine servicing based on a predetermined schedule. This approach often involves regular inspections, lubrications, adjustments, and part replacements at specific intervals, regardless of the equipment's current operational condition. The schedule is determined through historical data, manufacturer recommendations, and best practices, ensuring that potential problems are addressed before they lead to significant downtime or costly repairs.

Unlike reactive maintenance, which occurs after equipment has failed, preventive maintenance seeks to minimize the occurrence of such failures. Predictive maintenance, on the other hand, uses monitoring tools and data analysis to predict when maintenance should be performed based on the actual condition of the equipment. Proactive maintenance encompasses strategies to improve system performance and extend equipment life but may not strictly follow a replacement schedule.
