The complete technical table is shown in the Specifications tab on this page.
| Breakaway force [N] | 4.5 |
|---|---|
| Dimension [d] [mm] | 40 |
| Dimension C h13 [mm] | 58 |
| Dimension C1 H13 [mm] | 43.7 |
| Dimension C2 [mm] | 1.85 |
| Dimension D1 [mm] | 38.5 |
| Footnote breakaway force | One wiper seal: Multiply value with factor 0.5 |
| Footnote friction force FR | 1. One wiper seal: Multiply value with factor 0.5 2. 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. |
| 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 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. |
| Format of linear bushings | – Closed |
| Friction coefficient μ | 0.001 ... 0.0025 |
| Length of linear bushing [mm] | 58.0 |
| Lubrication | Not lubricated |
| Maximum acceleration rate amax [m/s²] | 150.0 |
| Maximum dynamic load capacity Cmax [N] | 4820.0 |
| Maximum permissible linear speed vmax [m/s] | 3.0 |
| Note: friction coefficient μ | Friction coefficients of unsealed linear bushings when lubricated with oil. The friction coefficient is lowest under heavy load, but can still be above the specified value even under a low load. |
| Note: maximum permissible speed vmax | Speeds of up to 5 m/s possible. Service life is limited by heightened wear to plastic parts. Tests have shown total travel from 50 • 10<sup>5</sup> m to 100 • 10<sup>5</sup> m without failure. |

| Series | Super B (no self-alignment feature) |
| Shaft diameter d [mm] | 25.0 |
| Type | Linear bushing |
| Version | Normal |
| Weight (Kg) | 0.14 |
