Recommended Minimum S₀
The critical factor for rolling contact surface deformation is peak amplitude, even if it occurs briefly. The following minimum values are recommended:
| Operating Condition | S0 |
|---|---|
| Suspended arrangement, high risk | ≥ 12 |
| High dynamic stress, shock loads | 8 – 12 |
| Normal machinery, moderate loads | 5 – 8 |
| All loads known, uniform & low vibration | 3 – 5 |

Carriage Load Distribution
Notes
- This calculation includes preload force effects.
- Results are based on DIN ISO 14728 theoretical formulas. Actual service life may vary depending on environment, lubrication, and installation accuracy.
- When S₀ < 3.0, a design reassessment is recommended.
