Vibration Analysis is used to detect early precursors to machine failure, allowing machinery to be repaired or replaced before an expensive failure occurs. Early detection of mechanical fatigue avoids breakdown. All rotating equipment vibrates to some degree, but as older bearings and components reach the end of their product life, they begin to vibrate more dramatically, and in distinct ways. Ongoing monitoring of equipment allows these signs of wear and damage to be identified well before the damage becomes an expensive problem.
