Refer to each graphregarding the maximum allowable moment and maximum allowable load for a particular piston speed.Load weight (kg)Moment (N·m)F1m1M1 = F1 x L1F2m2M2 = F2 x L2 F3m3M3 = F3 x L3Maximum 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.MY1M/M1200Moment (N·m)10050403020105432MY1M63MY1M50MY1M40MY1M32MY1M25MY1M/M2Moment (N·m)504030201054321MY1M63MY1M50MY1M40MY1M32MY1M25MY1M20MY1M/M3Moment (N·m)2010543210.50.40.30.2MY1M63MY1M50MY1M40MY1M32MY1M25MY1M20MXMTSMYCYMGCXD--X20-DataL1L2L31MY1M20MY1M160.50.40.3MY1M160.1MY1M161. 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 factorsNote 1) Moment caused by the load, etc., with cylinder in resting condition.Note 2) Moment caused by the impact load equivalent at the stroke end (at the time of impact with stopper).Note 3) Depending on the shape of the workpiece, multiple moments may occur. When this happens, the sumof the load factors (∑α) is the total of all such moments.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)Σα = + + ≤1Load weight [m]Maximum allowable load [mmax]·FE·L1 = 4.57υaδmL1 (N·m)Static moment [M] (1)Allowable static moment [Mmax]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 )Dynamic moment [ME] (2)Allowable dynamic moment [MEmax]2. Reference formula [Dynamic moment at impact]Use the following formulae to calculate dynamic moment when taking stopper impact intoconsideration.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 timeof stopper impact according to service life calculations.3. For detailed selection procedures, refer to pages 8-11-38 to 8-11-39.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. Therefore, also checkthe allowable moment for the selectedconditions.L1υmFEME0.5 100 200 300 400 500 1000 1500MY1M/m1Load weight (kg)200100504030201054321Piston speed (mm/s)MY1M63MY1M63 MY1M50MY1M40MY1M32MY1M25MY1M20MY1M16Load weight (kg)0.2100 200 300400 500 1000 1500Piston speed (mm/s)MY1M/m210050403020105432MY1M63MY1M50MY1M40MY1M32MY1M25MY1M201 MY1M160.50.4Load weight (kg)0.05100 200 300400500 1000 1500Piston speed (mm/s)MY1M/m3302010543210.50.40.30.2MY1M63MY1M50MY1M40MY1M32MY1M25MY1M20MY1M16100 200 300 400500 1000 15000.3100200 300400500 1000 15000.1100 200 300400500 1000 1500Piston speed (mm/s)Piston speed (mm/s)Piston speed (mm/s)8-11-368-11-37
