Engineering Competence

A major step forward in life modeling

In the recent Hannover Messe (April 2015), Alrik Danielson, SKF Group president and CEO, and Bernd Stephan, senior vice president, Group Technology Development, announced the concept launch of the SKF Generalized Bearing Life Model (GBLM), an innovative new bearing rating life model that is designed to help engineers calculate bearing rating life in a more realistic manner. The new model is a major step forward for the industry and will play an important role in enabling OEMs and end users to better match bearings and applications, resulting in improved machine life and reduced operating costs.

Developed as part of the SKF EnCompass Field Performance Program, this new model builds on the strengths of the current bearing life model – developed by SKF over 30 years ago – by successfully separating surface failure modes from subsurface failure modes. By encompassing more parameters, this model provides new insight into the calculation of bearing rating life.

The concept launch at Hannover Messe included two daily live interviews with the GBLM experts, demonstration of the calculation method by means of demonstrator software and one-on-one inter-action with customers and journalists. The concept model was very well received by the audience and customers, reviving the interest in bearing rating life

Hereafter, the fundamentals of the new model are presented.
