The Formula Explained
\( L_{10} = \left(\frac{C}{P}\right)^3 \)
Glossary of Variables
- Dynamic Load Rating (C): The bearing's capacity to support dynamic loads.
- Equivalent Load (P): The load acting on the bearing considering all forces.
- Speed (n): The rotational speed of the bearing.
How It Works: A Step-by-Step Example
For a bearing with a dynamic load rating of 1000 N, equivalent load of 500 N, and speed of 3000 RPM, the expected life is calculated as follows:
\( L_{10} = \left(\frac{1000}{500}\right)^3 = 8 \) million revolutions.
