Case Study: Detecting Bearing Defects on Yankee Roll
Throughout the presentation I will be sharing a case study that happened this year, we monitored a defect on our Yankee roll bearings that resulted to take the call to change the bearings that costs 50,000 Euro and stopping the plant for 3 days to make the maintenance activities.

Five Minute Facts
What Are Rolling Element Bearing Defects And What Causes Them?
Rolling element bearing defects are typically artifacts of mechanically induced stresses or lubrication issues that create small cracks or defects within the mechanical components of the bearing, leading to increased vibration.

The Detection of Gear and Bearing Defects Using Electrical and Current Signature Analysis
In this presentation we will discuss how to use ESA/MCSA to detect bearing and gear defects in a variety of driven equipment including geared elevators, cooling towers, and other applications, even when we are looking at a few RPM. We will discuss how to determine the correct frequencies as well as how to determine the defect severity amplitudes in -dB, and how to isolate the machine you are testing from nearby machines. Several case studies will be presented including an AC building elevator, a cooling tower, and at least one complex (multi-stage) gearbox using both data collection and continuous monitoring.

Making It In A High Frequency World Striving for High-Frequency Industrial Accelerometers
As predictive maintenance teams in industrial facilities strive for a more complete picture of their equipment’s health, high frequency vibration measurements have become a crucial addition to identify faults such as motor and pump bearing defects and gear tooth inconsistencies in high-speed gearboxes. As a result, there is an upsurge in demand for vibration sensors with a high frequency response.
