Predictive Maintenance increases machine life, reliability, and conformance while decreasing catastrophic failure, unscheduled downtime, and maintenance costs.

4. Why Equipment Fails ASLE Bearing Workshop M.I.T. Study Rabinowicz, 1981 Equipment Fails Because Obsolete 15% Surface Degrade 70% Accident 15% Wear 50% Corrosion 20% Fatigue Wear Damage resulting from Micro-cracks loading Abrasive Wear Damage resulting from Abrasive particles between Two moving surfaces Adhesive Wear Damage resulting from Metal surfaces dragging Over each other Caused by Water in oil, degraded oil, Process contamination, Coolant, condensation… Caused by Misalignment, imbalance, Improper fit / assembly, Secondary damage Caused by Abrasive particles in oil, Dirt, secondary wear, Process contamination Caused by Inadequate lubrication Low visc, no oil, high temp, Excess load, slow speed..

9. Proactive Maintenance Proactive Maintenance uses both analytical and physical evidence to eliminate the causes of problems. The two key components are Root Cause Analysis (RCA) and Failure Mode Effects Analysis (FMEA). FMEA is a thought process performed where every conceivable failure mode is analyzed and assessed as to Probability and Criticality . All correctable probabilities are fixed or eliminated. RCA is a methodology where evidence is examined after failure to determine the cause of failure . Often predictive tools such as Oil Analysis and Vibration Analysis are used to explain the failure mode. Corrective action is taken to eliminate or reduce the probability of a reoccurring problem.

11. Niccolo Machiavelli "The Prince" 1532 It must be remembered that there is nothing more difficult to plan, more doubtful of success, nor more dangerous to manage, than the creation of a new system. For the initiator has the enmity of all who would profit by the preservation of the old institutions and merely lukewarm defenders in those who would gain by the new ones. Why Selling A Cultural Change is so Hard Degrees of Success and Failure
