The load capacity for a ballscrew listed here is based on ISO 3408 / DIN 69051 calculations. This dynamic load capacity is the axial load Fm*, under which the ballscrew will show a service life of 1 million revolutions (L10 rating). To compare ISO 3408/DIN 69051 with ANSI 5.48 1977, load capacity Ca and service life must be converted in Pi and B10 rating. |
 |
| Fm | = Dynamic equivalent axial load [N] |
| Fm1 | = Dynamic equivalent axial load [LBS] |
| Ca | = Dynamic axial load capacity [N] |
| L10 | = Nominal service life [106 rev.] |
| P | = Lead [mm] |
| Pi | = Dynamic axial load capacity [LBS] ANSI 5.48 |
The resulting actual service life expectancy should be within the range:
It is not recommended to rely on service life expectancies that lie outside the above stated range.
