Read how SAM4 caught motor bearing failure in a runout table roll 7 months in advance for this steel manufacturer.
An increase in intensity at the bearing cage (FTF) frequency and its harmonics caused SAM4 to flag the motor for closer observation. We alerted the customer to developing but non-urgent damage. Over the next 7 months we sent the customer regular status updates. When the rise in intensity eventually reached a level that warranted timely action, the customer replaced the motor and roll during a scheduled maintenance window, after which intensities returned to normal. No unplanned downtime was incurred, thanks to SAM4’s early alert.
