| 1) | The load ratings apply for the main direction of loading. |
| The load ratings are based on a total travel of 100, 00 m. When based on 50 000 m, the values in the table need to be multiplied by 1.26. |

Main direction of loading
Load direction factors
The load ratings C and C0 apply for the load direction ρ = 0°. For all other load directions, the load ratings must be multiplied by the factors fr (dynamic load rating C) or fρ0 (static load rating C0).

Reduced load capacity with short stroke
In case of short stroke, the service life of the shaft is less than that of the super Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .
| 1) | fs = factor |
| 2) | s = movement path |
Reduced load capacity with high load
The load rating is reduced under high load F. The dynamic load rating must be multiplied by the load factor f.F .
| 1) | fF = load factor |

Super Linear Bushings can be installed in any location. Choose a location that ensures that the main direction of loading is always ρ = 0°.
