Calculation method
The rating life is calculated as follows:
Basic rating life
L10 or L10h
The basic rating life in millions of revolutions (L10) and the basic rating life in operating hours (L10h) are calculated as follows:
Rating life in revolutions
Rating life in operating hours
Parameters
L10 106 Basic rating life in millions of revolutions, which according to statistics is achieved at least 90% of the time, i.e. before the first signs of material fatigue
L10h h Basic rating life in operating hours, which according to statistics is achieved at least 90% of the time, i.e. before the first signs of material fatigue
C N Basic dynamic load rating, see product table
P N Equivalent dynamic load
p - Life index; for roller bearings: p=10/3, for ball bearings: p=3
n min-1 Operating speed (nominal speed)
