The master rail is imprinted with "KB" following a serial number.Table26 LM Rail Length and Running Parallelism by Accuracy StandardLM rail length (mm)Running Parallelism ValuesSuperprecisiongradeUltraprecisiongradeItem No Symbol H P SP UPDimensional tolerance in height M ±0.1 ±0.05 ±0.025 ±0.015 ±0.01Difference in height M Note 1) 0.03 0.02 0.01 0.005 0.003Dimensional tolerance for total width W0 ±0.1 ±0.05Difference in total width W0 Note 2) 0.03 0.015 0.01 0.005 0.003Parallelism of the raceway against surfacesA and BAbove Or less Normal gradeAW0High-accuracygradeΔC (as shown in Table26)Precision gradeSuper precisiongradeUnit: μmUltra precisiongrade— 50 5 3 2 1.5 150 80 5 3 2 1.5 180 125 5 3 2 1.5 1125 200 5 3.5 2 1.5 1200 250 6 4 2.5 1.5 1250 315 7 4.5 3 1.5 1315 400 8 5 3.5 2 1.5400 500 9 6 4.5 2.5 1.5500 630 11 7 5 3 2630 800 12 8.5 6 3.5 2800 1000 13 9 6.5 4 2.51000 1250 15 11 7.5 4.5 31250 1600 16 12 8 5 41600 2000 18 13 8.5 5.5 4.52000 2500 20 14 9.5 6 52500 3000 21 16 11 6.5 5.5LM GuideIndustrial TechnologiesA1-99
