What to do if the braking action is insufficient in Stromag KMB-ZM Industrial Equipment?

A
amandasmithAug 3, 2025
If the braking action of your Stromag Industrial Equipment is insufficient, it could be due to several reasons. One potential cause is that the inner disc was not degreased when it was replaced. In this case, degrease the friction surface. Another reason might be that the permissible wear has been exceeded, so replace the disc pack. Finally, there might be residual pressure present in the pressure line, so check the cause and find a corrective action.
