A rolling bearing goes through four failure stages - from the first micro-cracks on the raceway to catastrophic failure. The earlier the stage at which a defect is caught, the cheaper and simpler the scheduled repair.
Two methods, one goal
SDT340 ultrasonic diagnostics hears high-frequency friction as early as failure stage 1-2 - long before the defect becomes visible in vibration or audible noise. That buys weeks to months of lead time to plan the repair.
Portable vibration analysis (Commtest, Bently Nevada) adds precise kinematics: exactly which element is damaged, whether there's imbalance, misalignment or a loose mount - data ultrasound alone can't provide.
Together, the two methods cover the full path of a bearing defect from onset to repair-ready, cutting the number of unplanned stoppages on rotating equipment.
