The standard in gear construction has undergone considerable improvements over the last four decades: Advances in materials technology, heat treatment, surface technology, but also tribology and calculation enable higher strength with simultaneous weight reduction and improved thermal design. 
The specific gearbox weights have been reduced by around 80% - but this also means increasing demands on the rolling bearings! Schaeffler has contributed significantly to this increase in performance through targeted research and development and constant increases in quality. Through intensive exchange of experience with gearbox manufacturers and the user industry, we have continuously increased the functionality and operational safety of our bearings, while minimizing power losses at the same time. Gearboxes with quality rolling bearings are efficient and reliable. For the highest power densities, Schaeffler offers gearbox bearings made of high-performance steel - performance increases of +30% are possible.
