Comparative measurements with HD Technologies on couch roll

This case study shows comparative measurements between SPM HD and HD ENV on a couch roll bearing in paper machine K25 at Romanian paper mill Vrancart S.A. Adjud.

To determine the most suitable measurement technique for this application, several methods were used on each measuring point, including SPM HD and HD ENV. In this particular case, it was concluded that both measuring techniques gave very similar results, providing early warning and clear indications of bearing damage. 

When the couch roll bearing was dismounted, severe outer ring damage was confirmed.
