Rotary Clamp Cylinder: Heavy Duty Type Series MK2PrecautionsBe sure to read this before handling.Refer to back page 1 for Safety Instructionsand “Precautions for Handling PneumaticDevices” (M-03-E3A) for Common Precautions.CautionClamp Arm Mounting1. Use a clamp arm that is available as an option.To fabricate a clamp arm, make sure that theallowable bending moment and the inertialmoment are within the specified range.If a clamp arm that exceeds the specified valueis installed, the internal mechanism in thecylinder could become damaged.Ensuring Safety1. If one side of the piston is pressurised bysupplying air with the clamp arm attached, thepiston will move vertically while the clamp armrotates. This operation could be hazardous topersonnel, as their hands or feet could getcaught by the clamp arm, or could lead toequipment damage. Therefore, it is importantto secure as a danger zone a cylindrical areawith the length of the clamp arm as its radius,and the stroke plus 20 mm as its height.Installation and Adjustment/Clamp Arm Removal and Reinstallation1. During the removal or reinstallation of theclamp arm, make sure to use a wrench or avise to secure the clamp arm before removingor tightening the bolt.This is to prevent the bolt tightening torquefrom being applied to the piston rod, whichcould damage the cylinder’s internal mecha-Mounting Bolt for MK2BMounting: Mounting bolt for through-hole type isavailable.Ordering: Add the word “MK2B” to the mountingbolt size.Example) M5 x 75 L (MK2B)FlatwasherMounting boltArm length l (cm)20108642Precautions for Designing and Mounting ArmsWhen arms are to be made separately, their length and weight should be within the followingrange.1. Allowable bending momentUse the arm length and operating pressure in Graph (1) to select an allowable bendingmoment loaded piston rod.Graph (1)MK250/63MK232/40MK220/25Operatingrange0.45 0.55 0.80.1 0.2 0.4 0.6 1Operating pressure (MPa)2. Moment of inertiaWhen the arm is long and heavy, damage of internal parts may be caused due to inertia.Use the inertia moment and cylinder speed in Graph (2) basing on the arm requirements.Graph (2)Moment of inertia (kg·m 2 )3 MK250/63210 –264210 –3642MK232/40MK220/25OperatingrangeWhen the arm length is 8 cm, pressure shouldbe less thanMK220/25: 0.45 MPaMK232/40: 0.55 MPaMK250/63: 0.8 MPa.When the arm’s moment of inertia is 5 x 10 –3kg·m 2 , the cylinder speed should be less thanMK232/40: 66 mm/sMK250/63: 120 mm/s.For calculating the moment of inertia, refer tofront matter 1, 2, back page 8.Note) The maximum piston speed is equivalentto approximately 1.6x the averagepiston speed.
