Especificaciones
Specifications
| Shaft diameter d [mm] | 25.0 |
| Version | Standard |
| Format of linear bushings | – Closed |
| Series | Super A (with self-alignment feature) |
| Type | Linear bushing |
| Seal | Without wiper seals |
| Lubrication | Not lubricated |
| Maximum dynamic load capacity Cmax [N] | 4820.0 |
| Maximum acceleration rate amax [m/s²] | 150.0 |
| Maximum permissible linear speed vmax [m/s] | 3.0 |
| 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. |
| Length of linear bushing [mm] | 58.0 |
| Outer diameter D [mm] | 40.0 |
| Permissible ambient temperature (min. ... max.) | -10 °C ... +80 °C |
| Friction coefficient μ | 0.001 ... 0.0025 |
| 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. |
| Weight [kg] | 0.14 |
| Footnote breakaway force | One wiper seal: Multiply value with factor 0.5 |
| 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. |
| Footnote friction force FR | One wiper seal: Multiply value with factor 0.5 |
| Breakaway force [N] | 4.5 |
| Dimension C h13 [mm] | 58 |
| Dimension C1 H13 [mm] | 43.7 |
| Dimension C2 [mm] | 1.85 |
| Dimension D [mm] | 40 |
| Dimension D1 [mm] | 38.5 |
