The distributor installed the Solid Oil bearings, at the same time establishing a five-year warranty package, which involved the initial assembly in the yeasting section and a yearly sampling of bearings from different positions in the section to send to SKF for analysis.
SKF’s analysis would check the condition of the bearings and how the lubricant in the bearings had been affected.
In the period 2006 to 2016, only two bearing replacements were carried out, completely in accordance with the warranty package plan. Although the replacement of standard deep groove ball bearings with Solid Oil bearings was more costly, Pågen saved at least 300 hours in scheduled stoppages. Viewed over a five-year period, Pågen has saved 20,000 euros in direct bearing costs. Thanks to condition-based maintenance, in which the bearings are sent for analysis at SKF, Pågen and SKF’s distributor have a clear understanding of the bearing condition and thus have been able to postpone the replacement of all bearings to a later date.
There has not been a single unplanned stoppage.

“There has not been a single [unplanned] stoppage,” says Olofsson, “and this has resulted in a considerable saving both in terms of time and money; Pågen has avoided wasting ingredients and doughs because they were forced to stop the entire plant.”
