Sum and Examination of Guide Load Factors∑α = α1 + α2 + α3 + α4 + α5 = 0.67 ≤ 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, considereither decreasing the speed, increasing the bore size, or changing the product series. This calculation can be easilymade using the “SMC Pneumatics CAD System”.Load MassAllowable MomentMY1M/m1Load mass kg200100504030201054321100 200 300 400 500 1000 1500Piston speed mm/sMY1M/M1Moment N·m200100(1) (2)MY1M63MY1M50MY1M40MY1M32MY1M25MY1M20MY1M16504030201054321(4)0.5 100 200 300 400 500 1000 1500Piston speedmm/sMY1M63MY1M50MY1M40MY1M32MY1M25MY1M20MY1M16MY1M/M2Moment N·m504030201054321(3)MY1M63MY1M50MY1M40MY1M32MY1M25MY1M200.50.4MY1M160.30.2100 200 300 400 500 1000 1500Piston speed mm/sMY1M/M3Moment N·m2010543210.50.40.30.20.1(5)0.05100 200 300 400 500 1000 1500Piston speed mm/sMY1M63MY1M50MY1M40MY1M32MY1M25MY1M20MY1M16979D--XIndividual-XTechnicaldata
