| 1) | Frictional drags generated by Linear Bushings with integrated wiper seals on two sides when not under radial load. The frictional drags depend on speed and lubrication. |
| 2) | Frictional drags generated by Linear Bushings with seals on both ends when not under radial load. This depends on speed and lubrication. |

| 1) | The load ratings indicated are minimal values as the orientation and direction of load cannot always be clearly defined. |
| 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. |

Effect of load direction on load rating
The listed load ratings should be chosen depending on installation in minimum or maximum position and should be based on the calculations. If the load direction is clearly defined and the Linear Bushings can be installed in maximum position, the load ratings Cmax. (dynamic load rating) and C0 max (static load rating) can be used. If aligned installation is not possible or the load direction is not defined, the minimum load ratings must be used.
Reduced load capacity with short stroke
In case of a short stroke, the service life of the shaft is less than that of the segmental Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .

Project planning information
Selection guide for operation under difficult conditions
For constantly humid or damp conditions caused, for instance, by water-based coolants/lubricants, we recommend the stainless steel Linear Bushing with parts made of steel in accordance with ISO 683-17 / EN 10088.
