Bearing Lubrication Monitoring

Lubrication, a double paradox for maintenance

Ninety nine percent of all bearings fail, and when they do, your production comes to a standstill

All maintenance departments agree: lubrication and greasing are among the essential tasks of regular equipment upkeep. And yet, and this is the first paradox, it is often the least well executed maintenance operation! The proof is that 40% of bearings "break" prematurely because of inadequate greasing.

In recent years, industry leaders have made significant financial investments in equipment and operator training. All with a single aim: detecting problems before they lead to expensive stoppages. And this is the second paradox: why create more problems with incorrect lubrication?

For greasing to be effective, it must be tailored to the real needs of rotating machinery (right time, right lubricant, right amount). A modern, fully developed ultrasonic detector is the answer.

With ultrasonic technology you can avoid the three common errors of bearing lubrication.

Error No.1: period-based lubrication

There are many parameters influencing equipment's need for grease (load, environment, temperature, etc.). It is crucial that all these factors are considered, not just a "timing" component based on a theoretical calculation.

Error No.2: over and under greasing

The second mistake to be avoided at all costs is to use too much or too little lubricant. Both actions lead to wear or premature breakage of the bearing, in the first case because of elevated temperature and friction, the second through metal-to-metal contact. Extended under-lubrication will cause the bearing to seize, and may lead to even more serious machinery damage.

Error No.3: using ultrasound solely in listening mode

Simply listening, without taking measurements and recordings, is certainly too subjective, and cannot be recommended. Operator hearing varies, with significant risk of recording transcription errors (measurement, grease type, etc.). Only comparative analysis of the status of the bearing, before and after greasing, is truly objective.
