    Bearing Rating Life Calculation “Rating life” is the bearing life calculated for 90% reliability. This is the amount of time that a group of apparently identical bearings will complete or exceed before the formation of a fatigue spall. The basic formula for calculating bearing L 10 rating life is: where: C = Dynamic Capacity (dN or Lbs)
