| 1) | Actual shaft diameter varies |
| 2) | The load ratings indicated are minimal values as the load direction 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. |

Reduced load capacity with short stroke
In case of short stroke, the service life of the shaft is less than that of the torque-resistant Linear Bushing. The dynamic load ratings C in the tables must therefore be multiplied by the factor fs .

| 2) | s = movement path |

Installation
Radial clearance: approx. ± 5 μm
Linear bushing and shaft for torque-resistant Linear Bushings with four ball guide grooves come separately. Align the tracks and wiper seals when inserting the shaft and make sure they are not skewed!
General mounting instructions
Initial lubrication
Linear bushings do not come with initial lubrication. Grease the Linear Bushings before use. Service life data is based on initial lubrication and relubricated Linear Bushings.
