Bearing Failures: Early Warning Signs You’re Missing and How Predictive Analytics Catches Them
How Predictive Analytics Catches The Early Warning Signs You’re Missing Bearing failures typically begin with small, repeatable impact vibrations and slow operating changes that humans often miss in periodic checks. Predictive analytics improves early detection by trending vibration and temperature against each machine’s baseline and by applying techniques like demodulation (envelope analysis) to uncover weak fault signatures earlier than traditional monitoring. What you’ll learn The early warning signs most plants overlook Why overall vibration thresholds miss early bearing damage How predictive analytics and envelope features reveal faults earlier A practical monitoring workflow and action checklist The problem: why early bearing failures are “invisible” 1) Early defects are weak and masked In the earliest stage, bearing damage produces tiny repeated impacts that can be buried under normal machine vibration. Envelope (demodulation) analysis is widely used because...
