GBLM benefits:
• 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 SR parameter

Conclusions
2 November, 2015 Slide 7
• 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
