The companies Cestriom GmbH and N-Dect GmbH have developed the RFS device, an innovative system for demagnetizing roller bearing rings. The special feature is the magnetic fluxing with a rotating field and thus the utilization of the closed magnetic circuit of the ring.
Demagnetization with rotating field coils generates a very low and homogeneously distributed residual magnetism in the ring. These are optimal preconditions for subsequent eddy current testing procedures, according to Marek Rohner, founder of Cestriom.
The system is available stand-alone from Cestriom for manual operation or for integration into automated processes. The rotating field demagnetizer RFS03 is for rings or rotationally symmetrical parts. The rotating field coils are also available directly integrated in the N-Dect Flexitest eddy current testing machines via N-Dect.
Cestriom is a technology and service company with a core focus on products for demagnetization. N-Dect develops automated testing machines such as its eddy current systems. Both companies are located in southcentral Germany, Cestriom in Buehl west of Stuttgart and N-Dect in Pretzfeld near Nuremburg. For more info, see www.cestriom.com and www.n-dect.de.
