Allowable moment of inertia 3 times higher Allowable moment of inertia is the same as Allowable Moment of Inertia (032, 040) (Heavy-duty type) Piston speed [trim's] Maintenance can be performed for all sizes. Seal kit and guide pin are replaceable. Magnetic field resistant auto ^ Standard stroke range has been expanded. Strokes have been added to the New MK series, making a wide range of strokes available. ("^ indicates the added strokes.) Head flanges are newly Mounting type has been added to suit a wide range of applications. Overall length is shortened. 3 tO 10 mm shorter than the MK2...

Bore Size Selection Note) Maximum piston speed is equivalent to approximately 1.6x the average piston speed. (Rough Indication) Calculate the operating conditions and operate this product within the allowable range. If the allowable range is exceeded, increase the bore size or use the MK2T series. (Refer to SMC Best Pneumatics No. 3 for details of the MK2T series.) Maximum piston speed [mm/s] Maximum piston speed [mm/s] Maximum piston speed [mm/s] Maximum piston speed [mm/s]

Bore Size Selection Note) Maximum piston speed is equivalent to approximately 1.6x the average piston speed. (Rough Indication) Calculation example when arms other than the options are used. • Calculate the moment of inertia of the clamping jig • Calculate the moment of inertia of the arm. ■(Calculation example> when the cylinder bore Size ÍS 032. Clamping jig: h • Calculate the actual moment of inertia. Calculation result (when the bore size is o32 and clamp stroke is 10 mm.)

Bore Size Selection Do not use the cylinder under the following environments: • An area in which fluids such as cutting oil splash on the piston rod • An area in which foreign matter such as particles, cutting chips, or dust is present • An area in which the ambient temperature exceeds the operating range • An area exposed to direct sunlight • An environment that poses the risk of corrosion A cylinder could malfunction or the non-rotating accuracy could be affected if a rotational force is applied to the piston rod. Therefore, observe the particulars given below before operating the cy- 1)...
