Predictive Maintenance Guides
Vibration analysis, oil analysis, thermography, and condition monitoring programmes — the techniques that detect failures before they cause unplanned downtime.
Predictive maintenance (PdM) uses condition monitoring data — vibration, temperature, oil analysis, ultrasound — to forecast when a machine will fail. This allows maintenance to be planned before failure occurs, reducing unplanned downtime while avoiding unnecessary preventive maintenance. PdM typically delivers 8–12% cost reduction versus time-based PM when applied to critical rotating equipment.
