Refer to each graphregarding the maximum allowable moment and maximum allowable load for a particular piston speed.m2m3Maximum Allowable MomentSelect the moment from within therange of operating limits shown in thegraphs. Note that the maximumallowable load value may sometimesbe exceeded even within theoperating limits shown in the graphs.Therefore, also check the allowableload for the selected conditions.MY1C/M1Moment (N·m)2001005040302010543MY1C63MY1C50MY1C40MY1C32MY1C25MY1C/M2Moment (N·m)504030201054321MY1C63MY1C50MY1C40MY1C32MY1C25MY1C20MY1C/M3Moment (N·m)504030201054321MY1C63MY1C50MY1C40MY1C32MY1C25MXMTSMYCYMGCXD--X20-DataF1L1M1= F1 x L1F2L2M2 = F2 x L2F3L3M3 = F3 x L32MY1C20MY1C161100 200 300400500 1000 15000.5100 200 300400 500 1000 1500MY1C16MY1C200.5MY1C16100 200 300400500 1000 15001. Maximum allowable load (1), static moment (2), and dynamic moment (3) (at the time ofimpact with stopper) must be examined for the selection calculations.∗ To evaluate, use υa (average speed) for (1) and (2), and υ (collision speed υ = 1.4υa)for (3). Calculate mmax for (1) from the maximum allowable load graph (m1, m2, m3) andMmax for (2) and (3) from the maximum allowable moment graph (M1, M2, M3).Sum of guideload factorsΣα = + + ≤ 1Load weight [m]Maximum allowable load [mmax]Static moment [M] (1)Allowable static moment [Mmax]Dynamic moment [ME] (2)Allowable dynamic moment [MEmax]Maximum Load WeightSelect the load from within the rangeof limits shown in the graphs. Notethat the maximum allowable momentvalue may sometimes be exceededeven within the operating limits shownin the graphs.

When this happens, the sumof the load factors (∑α) is the total of all such moments.2. Reference formula [Dynamic moment at impact]Use the following formulae to calculate dynamic moment when taking stopper impact intoconsideration.m: Load weight (kg)F: Load (N)FE: Load equivalent to impact (at impact with stopper) (N)υa: Average speed (mm/s)M: Static moment (N·m)Note 4)υ = 1.4υa (mm/s) FE = 1.4υa·δ·m·g∴ME =13Note 5)·FE·L1 = 4.57υaδmL1 (N·m)υ: Collision speed (mm/s)L1: Distance to the load , s center of gravity (m)ME: Dynamic moment (N·m)δ : Damper coefficient At collision: υ = 1.4υaWith rubber bumper = 4/100(MY1B10, MY1H10)With air cushion = 1/100With shock absorber = 1/100g: Gravitational acceleration (9.8 m/s 2 )Note 4) 1.4υaδ is a dimensionless coefficient for calculating impact force.1Note 5) Average load coefficient (= 3): This coefficient is for averaging the maximum load moment at the time ofstopper impact according to service life calculations.L1υmFEMELoad weight (kg)504030201054321MY1C63MY1C50MY1C40MY1C32MY1C25MY1C20MY1C16Load weight (kg)504030201054321MY1C63MY1C50MY1C40MY1C32MY1C25MY1C20MY1C16Load weight (kg)543210.50.40.3MY1C63MY1C50MY1C40MY1C32MY1C25MY1C20MY1C163.
