Abstract

To achieve both further reduction of torque and extended life of rolling bearings, NSK is deriving a theoretical formula to predict the time until oil film collapse in the EHD contacts (i.e., Lubrication life). In this invited lecture, an overview of the lubrication life prediction project launched by NSK will be presented.
