Bearing Inspection

The bearings are essential components for the industry and are present in any factory. There are many types of bearings but when they present a fault or mechanical failure they all emit a noise in the ultrasound field.

The ultrasonic emission is generated by a change of the friction coefficient which can be generated by several factors such as incorrect lubrication (hyperlubrication or hypolubrication) or the wear of one or more components of the bearing.

In fact, one of the major cause of excessive stress machinery is friction.

The analysis of the ultrasound is effective at any rotational speed of the bearings (high, medium or low). In addition, given that ultrasound it is short-wave high-frequency, it is easy to filter out background noise and focus on the specific element to be inspected.

Ultrasound is the fastest technology in detecting mechanical problem, this allows you to have more time to plan and implement corrective actions. Early detection also allows you to eliminate the fault even when you are not in an emergency situation while saving about the corrective action.

HOW THE INSPECTION ULTRASONIC BEARING

There are three methods to monitor the bearings with Ultrasound:

• Comparative: comparing bearings of the same type and observe deviations
• Historical: setting the trend of the measured values ​​over time
• Analytical: Spectralyser use the software, with computer failures in the bearings integrated.

With the historical method you can program the alarm levels:

Establish a reading of baseline

• 1° alarm indicates poor lubrication
• 2° alarm early warning of failure
