Preventive maintenance is a proactive approach aimed at preventing equipment failures before they occur. This type of maintenance typically involves regular inspections and servicing based on a predetermined schedule, which can be guided by manufacturer recommendations or operational experience.

The key aspect of preventive maintenance is its focus on routine checks and servicing tasks such as lubrication, adjustments, and part replacements, which help to enhance the reliability and efficiency of equipment. By addressing potential issues before they evolve into significant problems, organizations can decrease downtime and extend the lifespan of their machinery.

In contrast, reactive maintenance refers to responding to equipment failures after they happen, while predictive maintenance leverages data and analytics to predict failures based on the condition of the equipment. Corrective maintenance, on the other hand, involves repairs after a malfunction has occurred. Each of these categories serves a different purpose, but preventive maintenance stands out for its emphasis on regular, scheduled activity to ensure operational continuity and equipment health.
