World's First Hybrid Bearing Life Model from SKF
Called the Generalized Bearing Life Model (GBLM), its development will ensure that SKF customers and distributors choose the right bearing for the right application, every time.Until now, it has been difficult for engineers to predict whether a hybrid bearing will outperform a steel one in a given application, or whether the possible performance benefits that hybrid bearings enable are worth the extra investment they require. The conventional equations engineers use to calculate the rating life of a bearing do not reflect the real-world performance of hybrid designs.To rectify this issue…
