Formula Used
L10 = (C/P)^p million revolutions. p = 3 for ball bearings and p = 10/3 for roller bearings. L10h = L10 x 10^6 / (60n).
Important
C and equivalent load P must come from manufacturer data and validated load calculation.
Engineering Calculation Notice
Calculations are estimation tools based on the inputs, formulas and assumptions shown. Actual performance may vary depending on machine configuration, materials, loading, temperature, dynamic effects and operating environment. Final manufacturing or safety-critical decisions should be reviewed by a qualified engineer.
