NSK ABLE Forecaster is a life equation that takes into consideration all operating conditions for determining service life. Fatigue load limit, lubricating conditions, contamination of lubricant, and difference of materials, which have not been considered in conventional life equations, are reflected precisely in ABLE Forecaster. By using this equation, users can predict bearing life easily and with greater accuracy. Further details can be found in the "HELP" of life calculation.


ABLE Forecaster calculates rolling fatigue life, which is defined as bearing life until the occurrence of flaking. Applicable to most operating conditions, with a few exceptions as listed below. Contact NSK for further details.
NAVI-FOCUS can compute the life calculation(ISO281:2007)and conventional life calculation(ISO281:1990). The conventional equation is listed in NSK General Catalog.
