Series MHL Gripping Point The workpiece gripping point distance should be within the gripping force ranges given for each pressure in the effective gripping force graphs below. If operated with the workpiece gripping point beyond the indicated ranges, the load that will be applied to the fingers or the guide will become excessively unbalanced. As a result, the fingers could become loosened and adversely affect the service life of the unit.

Parallel Style Air Gripper: Wide Type Series MHL Selection Example Procedure Confirmation of conditions Select possible points according to the work length Calculation of required gripping force Selection of model from gripping force graph Work form Diameter x Length mm x mm plate Work mass:.3 kg Gripping point R = 7 mm Operating pressure:.5 MPa It is not particularly necessary to locate the workpiece; if the air gripper is to be used by merely hooking the workpiece to the attachment, consult SMC. Work length: From the dimensions of models that have an opening width of mm or more MHL-6D MHL-D/D MHL-5D/D Guidelines for the selection of the gripper with respect to component mass Although conditions differ according to the workpiece shape and the coefficient of friction between the attachments and the workpiece, select a model that can provide a gripping force of to times the workpiece mass, or more. Further allowance should be provided when great acceleration or impact is expected during workpiece transfer. Example) For setting the gripping force to be at least times the workpiece mass: Required gripping force =.3 kg x x 9.8 m /s N MHL-D 8 73 Pressure.6MPa.5MPa.4MPa.3MPa.MPa 8 7 Selecting the MHL-D A gripping force of 73 N is obtained from the intersection point of gripping point position R = 7 and a pressure.5 MPa. The gripping force is 4 times greater than the workpiece mass, and therefore satisfies a gripping force setting value of times or more.
