According to statistics, there are more than 50 billion bearings being manufactured during the past 5 years around the world. Only a relatively small percentage of all bearings in use fail. Majority (90%) of the bearings outlive the equipment in which they have been installed.

Remote condition monitoring of bearings and precision lubrication executed anywhere, anytime, and from any device, is already a reality. Pairing the Internet of Things with Ultrasonic sensors has brought the development of innovative maintenance solutions that will take condition monitoring of assets to a whole new level, allowing maintenance teams to stop most bearing failures at its tracks.

Vibration Monitoring is the most commonly used condition monitoring method for rotating machines. Since resources are limited and we have a variety of Vibration Monitoring techniques, we have to ensure that our selection of VM technique is justifiable, hence it's required to follow a systematic procedures which are structured based on reasonably agreed criteria.

More than 300 million electric motors are used in infrastructure, large buildings, and industry globally. These motors account for about 2/3rds of the industrial power consumption. Electricity is required in almost all areas of the plant to provide the driving force that either operates the equipment that produces the products or provides the services that the plant’s equipment was built to perform..

Variable frequency drives (VFDs) have become a preferred method of process control for electric motor driven equipment ranging from vertical water pumps to centrifugal air fans. The following is a basic discussion of risks of using a VFD with direct driven centrifugal fans and methods of mitigating those risks to maintain equipment reliability.

Studies show that 50 to 70% of all equipment failures can be directly traced to a lubrication-related issue, most of which can be found with oil analysis.
A small number of semiconductor manufacturers have overcome the noise, bandwidth and g-Range shortcomings commonly associated with MEMS sensors used in Condition-based Monitoring (CbM) by producing several medium and high-performance MEMS vibration sensors with the latter being comparable to piezo accelerometers.

Businesses invest millions of dollars in what they believe will be a fail-safe maintenance program for their electric motors. Regular tests are scheduled for each motor; engineers dutifully record the data when required and then move on to the next motor.
