23 7 A B 2 MINIRAIL Product Overview 7.2 MINIRAIL Product Overview 7.2.3 Accuracy Classes MINIRAIL carriages and guide rails are made to a high precision independently of each other. The carriages are interchangeable. This means that any carriage of the same size and accuracy class can be used on the guide rails without influencing the preload class. MINISCALE PLUS carriages and guide rails are also made to a high precision. Due to the integrated linear encoder, the carriage and guideway are matched together and therefore can only be changed as a set. Both G1 and G3 accuracy classes offer a precise MINIRAIL range suited to the application-specific needs of the customer. The accuracy classes determine the size tolerances and the running accuracy of the carriages on the guideways: High accuracy G1 Standard accuracy G3 Note: MINIRAIL are available in accuracy classes G1 and G3 MINISCALE PLUS are always delivered in accuracy class G1. Tolerances A and B 2 ΔA and ΔB 2 Accuracy class G1 +/- 10 µm  7 µm Accuracy class G3 +/- 20 µm 15 µm Measured relative to carriage centre Difference in measurement between several carriages on the same position on the rails For the measurements mentioned above, the guideway is mounted on a flat surface. Measurement is taken from the middle of the carriage. Since the measure- ment is stable, it is based on the midpoint of the two supporting surfaces Marked side Reference side
