Use consistent units and the requested inputs.
Use the main result and breakdowns as a planning estimate.
For regulated topics, verify current local rules before acting.
L10 = (C/P)^(10/3) million revolutions (roller bearing; ISO 281 basic life)
Inputs: c=65 kN; p=18 kN. Apply the stated formula.
Preliminary ISO 281 L10 fatigue life, not a bearing service-life or safety certification.
ISO 281 basic L10 is a statistical rolling-contact fatigue life at 90% reliability, NOT a guaranteed replacement interval or proof of safe operation. C and equivalent dynamic P must both use kN; P is already an input, NOT computed from radial/axial loads here. Ball exponent is 3 and roller exponent 10/3. A C/P ratio below 1 gives an L10 below one million revolutions; it must not be hidden, although such high loading may independently violate static safety/deformation or load/application limits. The basic model excludes lubrication, contamination, mounting, misalignment, speed variation, temperature and life-modification factors. Hour conversion assumes constant speed; calendar conversion assumes the entered constant daily use and 365 days/year. Numerical input window is not a certified bearing operating range.
