| Footnote minimum dynamic load capacity Cmin | The dynamic load capacities are based on a total travel of 100,000 m. When based on 50,000 m, the C values in the table are to be multiplied by 1.26. |
| Footnote maximum dynamic load capacity Cmax | The dynamic load capacities are based on a total travel of 100,000 m. When based on 50,000 m, the C values in the table are to be multiplied by 1.26. |
| Footnote friction force FR | Frictional drags generated by linear bushings with seals on both ends when not under radial load. This depends on speed and lubrication. |
