The end customer produces viscose fibers for a wide variety of applications, such as sanitary materials or tea bags. In an electric motor with a frequency converter, the bearings had to be replaced 6 times a year due to electrical corrosion. NSK recommended the use of current-insulated deep groove ball bearings. After that, there were no more unplanned failures. This drastically reduced the costs associated with production downtime.
