Sum and Examination of Guide Load Factors∑α = α1 + α2 + α3 + α4 = 0.39 ≤ 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 easily made using the “SMC Pneumatics CAD System”.MY1BMY1MMY1CMY1HMY1HTMY1WMY2CMY2HMY3AMY3BMY3MMY1HT/M11000MY1HT/M31000500500300300Moment (N·m)10050MY1HT50MY1HT63Moment (N·m)100MY1HT5050MY1HT63(1)(2)(3) (4)40304030D-2020-X10100 200 300 400 500 100010100 200 300 400 500 1000Piston speed (mm/s)Piston speed (mm/s)1043Individual-XTechnicaldata
