4 Bearing life knowledge Bearing Life Calculation journey SKF GBLM Weibull s weakest link theory Lundberg & Palmgren Dynamic capacity 1947 Ioannides & Harris Fatique limit model 1985 Bearing surface life model 2012 SKF Insight SKF Generalized Bearing Life Model SKF Insight Bearing Health Management 1938 Time Slide 4

5 SKF Generalized Bearing Life Model Surface: Tribology models Sub-Surface: Hertzian Rolling Contact Fatigue L ) 10GM fss ( C, Rss ) fs ( Rs, p1, p2 b internal geometry heat treatment surface finish contamination resistance subsurface surface wear resistance reduced vibration longer service life lower noise load rating limiting speed steel composition coatings lubrication reduced friction reduced vibration corrosion resistance Slide 5

6 GBLM Calculation SKF Generalized Bearing Life Model GBLM benefits: on Separates surface from subsurface and use advanced tribological models for surface reliability modelling Provides unique representation to specific surface features and quality For the first time, gives indication of the risk area of the bearing with the S R parameter Slide 6

7 Conclusions The GBLM is built on the strength of the current Modified Rating bearing model of SKF and ISO 281 but adds more flexibility and new knowledge. GBLM allows the user to clearly separate surface from subsurface risks and failure modes. GBLM introduces performance factors that can reflect special design features of SKF bearings and can target specific region of the operating conditions GBLM surface tribology model allows SKF together with our INSIGHT bearing sensor technology to manage active the machine health and to extend the real life Slide 7
