BearingLifeAdjustmentFactorForOperatingConditions
Operating conditions which remain to be taken into account here include the adequacy of the lubrication (at the operating speed and temperature), presence of foreign matter, conditions causing changes in material properties (for example high temperature causing reduced hardness) and mounting conditions. The influence on bearing life of such conditions may be taken into account by the introduction of the Life Adjustment Factor for Operating Conditions. From section 8.5 of ANSI/ABMA 9:2015 and ANSI/ABMA 11:2014.
