  • Bearing rating life | SKF

    The rating life L 10 is the fatigue life that 90% of a sufficiently large group of identical bearings operating under identical conditions can be expected to attain or exceed. The rating life L 10 is a proven and effective tool which can be used to determine a bearing size that is adequate to avoid fatigue failures.

  • Bearing Life Calculation - Bearing Loads & Speeds

    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)

    2004-5-26 · In a sealed deep groove ball bearing operating at n x d m =300,000 and 55°C, a grease with GPF=1 is the best solution, giving L 10 =30,000 hours. For GPF=2 the estimated life is the same, whereas a grease with GPF=4 is not recommended, due to a shorter life.
