| ML | Nm |  | 3960 | 8160 |
| ML0 | Nm | 6990 | 14800 | |
| The calculation of the dynamic load ratings and load moments is based on a stroke length of 100,000 m as per DIN ISO 14728-1. However, often only 50,000 m is actually stipulated. For comparison: Multiply the values C,Mt and ML from the table by 1.26. |

General Notes
The general technical data and calculations apply to all Ball Rail Systems i.e. to all Ball Runner Blocks and Ball Guide Rails. Specific technical data relating to the individual Ball Runner Blocks and Ball Guide Rails is listed separately.
Preload classes
To cover the widest possible range of applications, Rexroth Ball Runner Blocks are available in different preload classes.
The following preload classes are available:
- Ball Runner Block without preload (preload class C0)
- Ball Runner Blocks with moderate preload (preload class C1)
- Ball Runner Blocks with average preload (preload class C2)
- Ball Runner Blocks with high preload (preload class C3)
To prevent reductions to the service life, the preload should not exceed 1/3 of the load on bearing F.
In general, the rigidity of the Ball Runner Block rises with increasing preload. If vibrations occur, select a correspondingly high preload (≥ preload class C2).
Guide systems with parallel rails
When choosing the preload class, pay attention to permissible parallelism offset of rails too ("Accuracy class selection criterion").
When specifying ball rail systems of accuracy class N, we recommend preload class C0 or C1 to avoid distortive stress due to the tolerances.
