Of direct relevance to the wind energy sector, international accredited registrar and classification society DNV GL has confirmed that roller and ball bearings made of NSK’s Super-TF material exhibit significantly higher dynamic load rating than the standard bearings.
Such is the effect of the higher load rating that bearing service life is effectively doubled in wind turbine applications.
The verification confirmed NSK's published specifications and, in a Statement of Conformity dated 15 November 2017, certified that when Super-TF material is used, the basic dynamic load rating can be improved by 23% in roller bearings and 26% in ball bearings. This is equivalent to a doubling of bearing fatigue life in comparison with ordinary bearings.
