A steel manufacturer was experiencing regular failures within its Ore Preparation Plant (OPP). The plant utilized housed bearing units installed on a 60mm shaft and ran at approximately 1485 rpm. NSK was informed that the bearing used was failing and requested to perform a vibration analysis on the current condition within the application. An ISO14836-2 qualified condition monitoring engineer visited the site to make an assessment. On replacement of the bearings, initial readings were taken by NSK and subsequent readings were then taken within the following weeks to trend the condition and predict where failures may occur.
|Before||Cost p.a.||NSK Solution||Cost p.a.|
|Cost of replacement and lost productivity from the blast furnaces:
The viral forces upon the housed units would have induced 1 additional failure over the predicted 2 year life time, thus a 20% saving.
