NSK's asset improvement programme is saving the operator of a Cold Rolling Mill #8364;16,300 annually as a result of solving a problem of bearing failure that was occurring three/four times per year, resulting in unplanned shutdowns and serious loss of production at the mill.
The mill operator was being forced to change bearings up to four times a year due to the harsh working environment in which the bearings operated. The bearings were failing prematurely due to contamination; ingress from dirt, debris and liquids that were affecting the bearing lubricant and shortening bearing life.
NSK was called in to find a solution to the failure problem. This involved engineers from the company in analysing the mill bearings, and taking samples of the lubricant used (grease) to determine the actual operating conditions. At the conclusion of the analysis, NSK recommended using spherical roller bearings manufactured from the company
