(495) 727-22-72*1: Running parallelismIt refers to the parallelismerror between the LM blockand the LM rail datum planewhen the LM block travelsthe whole length of the LMrail with the LM rail securedon the reference datumplane using bolts.*2: Difference in height MIt indicates the differencebetween the minimum andmaximum values of height(M) of each of the LMblocks used on the sameplane in combination.Accuracy StandardThe accuracy of model SHW is specified in terms of running parallelism ( *1 ),dimensional tolerance for height and width, and height and width differencebetween a pair ( *2, *3 ) when two or more LMblocks are used on one rail or when two ormore rails are mounted on the same plane.The accuracy of model SHW is categorized into Normalgrade (no symbol), High-accuracy grade (H), Precision grade (P),Super-precision grade (SP) and Ultra-super-precision grade(UP) by model numbers,as indicated in the table below.*3: Difference in width W2It indicates the differencebetween the minimum andmaximum values of thewidth (W2) between each ofthe LM blocks, mounted onone LM rail in combination,and the LM rail.Model No.12141721273550Accuracy standardsItemC AD BC AD BC AD BC AD BNormal gradeNo symbol0.070.0150.040.020.070.020.060.020.080.020.070.0250.080.0250.070.03High-accuracy gradeH0.030.0070.020.01Precision gradeP0.0150.0050.010.006as shown in the table belowas shown in the table belowas shown in the table belowas shown in the table belowSuper precision grade Ultra precision gradeSP0.0070.0030.0070.004UP0000.03– 0.03– 0.015– 0.0080.01 0.006 0.004 0.0030000.03– 0.02– 0.015– 0.0080.01 0.006 0.004 0.0030000.04– 0.04– 0.02– 0.010.015 0.007 0.005 0.0030000.03– 0.03– 0.015– 0.010.015 0.007 0.005 0.003as shown in the table belowas shown in the table below0000.04– 0.05– 0.03– 0.0150.015 0.007 0.005 0.0030000.04– 0.04– 0.025– 0.0150.015 0.007 0.005 0.003as shown in the table belowas shown in the table belowUnit: mmLM Rail Length and Running Parallelism by Accuracy of model SHWUnit: mLM rail length (mm)Running Parallelism ValuesAboveOr lessNormal grade High-accuracy grade Precision grade Super precision grade Ultra precision gradeNo Symbol H P SP UP 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 3150 21 16 11 6.5 5.53150 4000 23 17 12 7.5 64000 5000 24 18 13 8.5 6.5
