Bearing Life (L10): How to Use Guide
Calculate L10 and L10h from C, P, type, and rpm. Step-by-step method, examples, common mistakes, standards, and related tools.
Problem Definition
Bearing Life (L10) is used to reduce manual errors and speed up engineering decision making when repeated calculations are needed.
Formula Explanation
Step-by-step flow:
- Define all inputs and units.
- Convert units to a consistent basis.
- Apply the core equation in sequence.
- Validate the output range and boundary conditions.
Decision flow:
Input -> Unit Check -> Formula -> Validation -> Decision
Worked Example
Start with the calculator defaults, change one input at a time, and compare the intermediate values against the displayed assumptions before accepting the final output.
Common Mistakes
- Mixing unit systems (mm vs m, bar vs Pa)
- Ignoring boundary conditions
- Rounding too early in intermediate steps
