Acoustic emission testing of bearings

Acoustic emission testing of bearings is a modern diagnostic method used to identify and prevent potential faults and damage in bearings. This technique is based on the detection of ultrasonic waves released from the bearing material due to internal friction and micro-movements of material particles, typically caused by incipient damage or wear.

As the bearing material operates under load, its internal structure may begin to change, leading to the release of acoustic emissions. These emissions are captured by sensors attached to the bearing and analyzed using specialized software. By analyzing these signals, not only existing damage can be identified, but often its cause can also be determined, and the possible development of the situation can be predicted.

This method allows for diagnostics to be performed without the need for device disassembly, bringing significant savings in time and financial resources, especially in industrial applications where downtime could have significant consequences. Acoustic emission testing of bearings thus becomes a key component of preventive maintenance and monitoring the condition of mechanical equipment.
