Reliable wireless triaxial measurements

Some of the most common defects in rotating machinery, such as imbalance or structural resonance, can occur in one direction.
To prevent a malfunctioning machine from going undetected, Bearing Defender performs triaxial measurements at once, not only to facilitate the measurement process, but also to keep your machine in good working order.
Thanks to its patented wireless measurements and metrological performance, Bearing Defender ensures that your rotating machines can continue to operate without risk.
