Periodic Report Summary 1 - IBETTER (improvement in Bearing Technology Through European Research Collaboration)

iBETTER is a research programme under the FP7 Industry – Academia Partnerships and Pathways scheme. The project involves collaboration between four partners: SKF Engineering and Research Centre (SKF ERC), the Netherlands, SKF Condition Monitoring Centre (SKF CMC), UK, Lulea University of Technology (LTU), Sweden and Imperial College London (IC), UK.

The project started on 1 September 2013. The main research objective of the programme is to integrate fundamental understanding of tribological contact with condition monitoring technologies in order to improve the performance of rolling element bearings and in particular, to provide an integrated prognostic methodology for reliable predictions of remaining useful life of a bearing operating in a machine. A successful implementation of such a methodology can substantially reduce the maintenance costs, downtime and safety risks associated with operation of mechanical systems. In addition, the strategic objective is to strengthen the collaboration and create new partnerships between the industrial and academic participants involved.
