3 Series /A/M Specific Product Precautions Be sure to read before handling. Warning 1. Tighten the screw within the specified torque range when mounting the air gripper. Tightening with a torque above the limit can cause malfunction, while insufficient tightening can cause slippage and dropping. How to Mount Air Grippers Axial Mounting (Body tapped) l Lateral mounting (Body tapped, body through-hole) Body tapped Mounting Warning. Do not scratch or dent the air gripper by dropping or bumping it when mounting. Slight deformation can cause inaccuracy or a malfunction. 3. Tighten the screw within the specified torque range when mounting the attachment. Tightening with a torque above the limit can cause malfunction, while insufficient tightening can cause slippage and dropping.

4 Selection Selection Procedure Series /A/M Selection Step 1 Confirm gripping force Step Confirmation of inertial moment of attachment Step 1 Confirmation of Gripping Force Confirmation of conditions Calculation of required gripping force selection from gripping force graph Example Workpiece mass: 0.01 kg Gripping method: External gripping Length of gripping point: 5mm Operating pressure: 0.MPa selection criteria with respect to workpiece mass Although differences will exist depending on factors such as shape and the coefficient of friction between the attachments and workpieces, select a model which will provide a gripping force to 0 times the (Note 1) weight of the workpiece. (Note 1) Refer to the model selection illustration for more information. Furthermore, in cases with high acceleration or impact, etc., it is necessary to allow an even greater margin of safety. Example: When it is desired to set the gripping force at times or more the workpiece weight. Required gripping force = 0.01 kg x x 9.8 m/s = Approx N or more -D/A-D Gripping force N Pressure 0. MPa Gripping point L mm Selecting the -D. The gripping force of 1.5 N is obtained from the intersection point of gripping point distance L = 5 mm and pressure of 0. MPa. The gripping force is 1.7 times greater than the workpiece weight, and therefore satisfies a gripping force setting value of times or more. Selection Illustration F μf mg Gripping force at least to 0 times the workpiece weight The " to 0 times or more of the workpiece weight" recommended by SMC is calculated with the safety margin of a =, which allows for impacts that occur during normal transportation, etc. μf When μ = 0. When μ = 0.1 mg F = x x 0. = x mg F mg F = x x 0.1 = 0 x mg When gripping a workpiece as in the figure to the left and with the following definitions, F: Gripping force (N) μ: Coefficient of friction between attachments and workpiece m: Workpiece mass (kg) g: Gravitational acceleration (= 9.8 m/s ) mg: Workpiece weight (N) the conditions under which the workpiece will not drop are x μ F > mg Number of fingers and therefore, mg F > x μ With "a" as the safety margin, F is determined as follows: mg F = x a x μ 18 x workpiece weight 0 x workpiece weight (Note) Even in cases where the coefficient of friction is greater than μ = 0., for safety reasons, SMC recommends selecting a gripping force which is at least to 0 times the workpiece weight. It is necessary to allow a greater safety margin for high accelerations and strong impacts, etc.

6 Series /A/M Step Confirmation of Inertial Moment of Attachment Confirm the inertial moment of one of the two attachments. For example, in calculating the inertial moment of an attachment in the picture on the left, divide it into rectangular parallelepipeds, A part and B part. A part B part Procedure Formula Example z.calculate the operating conditions and attachment dimensions. A part B part f e b c a Operating equipment: -D a = 0 (mm) b = 3 (mm) c = (mm) d = (mm) e = 5 (mm) f = (mm) d x.calculate the inertial moment of the attachment. A part z1 f1 z Assuming the attachment material is aluminium alloy (relative density=.7), r1 = 1. (mm). Inertial moment around Z1 axis 1Z1 = {m1 (a + b ) / 1} x - Inertial moment around Z axis 1A = 1Z1 + m1r1 x - z B part z f Mass calculation m1 = a x b x c x Relative density m1 1Z1 1A r = 0 x 3 x x.7 x - =.8 x - (kg) = {.8 x - x (0 + 3 )/1} x - =.1 x -8 (kg. m ) =.1 x x - x 1. x - = 0.0 x - (kg. m ) = 3.5(mm) c.confirm from the table that the inertial moment of one attachment is within the allowable range. Inertial moment around Z axis 1Z = {m (d x e ) / 1} x - Inertial moment around Z axis 1B = 1Z x mr x - Mass calculation m = d x e x f x Relative density Thus, the total inertial moment is 1 = 1A + B -D/A-D Finger opening and closing speed Without speed controller With speed controller 3/ to 1 and 1/ reverse rotation from fully close state ( : Unit conversion constant) Allowable inertial moment of attachment 0.5 x - Kg m 1.5 x - Kg m Attachment inertial moment > Allowable inertial moment m = x 5 + x.7 x - = 3. x - (kg) 1Z 1B 1 = {3. x - x ( + 5 ) / 1} x - = 1.11 x -9 (kg. m ) = 1.11 x x - x 3.5 x - = 0.18 x - (kg. m ) = 0.0 x x - = 0.38 x - (kg. m ) Attachment inertial moment 0.38 x - (kg. m ) < Allowable inertial moment without speed controller 0.5 x - (kg. m ) Therefore, the attachment can be used without a speed controller. 0

Note) In the case of M-7S, provide a run off space because the speed controller protrudes from the body top surface by 0. mm. Note) Sometimes the workpiece may not be gripped precisely because of excessive speed in finger opening and closing. Therefore, use a meter-in type speed controller to adjust the finger opening and closing speed. 1
