Micro-pitting in bearings is often a sign of future bearing failure. However, because the development of micro-pitting occurs on a microscopic level, damage from micro-pitting is difficult to identify prior to failure with standard inspection techniques.
High-Frequency Signal Analysis provides an effective option for identifying micro-pitting damage. This technique monitors vibration along with the detection of acoustic emissions that have characteristic patterns for surface fatigue that occur prior to significant defects forming.
The early warning that High-Frequency Signal Analysis provides supports teams that utilize predictive maintenance programs via their ability to:
-Identify faults prior to their onset (i.e., sooner).
-Reduce unplanned production interruptions (i.e., reduce unanticipated down time).
-Extend bearing life.
-Improve reliability of assets.
As the technologies of industrial condition monitoring continue to be enhanced, the use of High-frequency Signal Analysis provides an increasingly effective option for implementation of proactive maintenance.
