| | | |
| | | | | | | | | | | Accuracy class | Tolerances 1 A and B2 | 2 A A and AB2 | | | | G1 | ± 10 pm | 7 um | | | | G3 | ± 20 um | 15 um | | | | 1 Measuring referring to the center of the carriage 2 Dimension differences between two or more carriages measured at the middle of each | | | | carriage (mean value of both supports) and at the same rail position | | | | | | | | | | |

| | | 2.3 Preload classes V0, V1 Preloading increases the rigidity of the guideway but also affects operational life and increases translation resistance. The MINIRAIL system is available in two preload classes to address specific application requirements. The rail up to determines the preload classes. | | |
| | | |
| | | | | | | | | | | Preload class | Preload | Accuracy class | | | | V0 | near clearance | G3 | | | | | to 0.01 • C | | | | | V1 | 0 to 0.03 • C | G1, G3 | | | | | | | | | | |
