Proactive maintenance is the
maintenance philosophy that supplants “failure reactive” with “failure proactive” by activities that avoid the underlying conditions that lead to machine faults and degradation. Unlike
predictive
A prediction (Latin ''præ-'', "before," and ''dicere'', "to say"), or forecast, is a statement about a future event or data. They are often, but not always, based upon experience or knowledge. There is no universal agreement about the exact ...
or
preventive maintenance, proactive maintenance commissions corrective actions aimed at failure root causes, not failure symptoms. Its central theme is to extend the life of machinery as opposed to
#making repairs when often nothing is wrong,
#accommodating failure as routine or normal, or
#detecting impending failure conditions followed by remediation.
Proactive maintenance depends on rigorous machine inspection and condition monitoring. In mechanical machinery it seeks to detect and eradicate failure root causes such as wrong
lubricant
A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, t ...
