Sum and Examination of Guide Load Factors∑α = α1 + α2 + α3 + α4 + α5 = 0.72 ≤ 1The above calculation is within the allowable value, and therefore the selected model can be used.Select a shock absorber separately.In an actual calculation, when the total sum of guide load factors ∑α in the formula above is more than 1, consider eitherdecreasing the speed, increasing the bore size, or changing the product series. This calculation can be easily made using the“SMC Pneumatics CAD System”.M2M3M1EFEM3EFEm2M1MY1BMY1MMY1CMY1HMY1HTMY1WMY2CMY2HMY3AMY3BMY3MLoad MassAllowable MomentMY1C/m2MY1C/M1200MY1C/M2MY1C/M3Load mass (kg)100504030201054321(1)100 200 300 400 500 1000 1500Piston speed (mm/s)MY1C63MY1C50MY1C40MY1C32MY1C25MY1C20MY1C16Moment (N·m)10050403020105432(2)(4)MY1C161100 200 300 400 500 1000 1500Piston speed (mm/s)MY1C63MY1C50MY1C40MY1C32MY1C25MY1C20Moment (N·m)5040302010543210.5(3)100 200 300 400 500 1000 1500Piston speed (mm/s)MY1C63MY1C50MY1C40MY1C32MY1C25MY1C20MY1C16Moment (N·m)50403020(5)10MY1C63MY1C5054MY1C40321MY1C32MY1C25MY1C200.5MY1C16100 200 300 400 500 1000 1500Piston speed (mm/s)999D--XIndividual-XTechnicaldata
