4 otary lamp ylinder/standard Series MK Precautions e sure to read before handling. efer to p.-3 to -4 for Safety Instructions and common precautions on the products mentioned in this catalog. aution Mounting of lamp rm q Use a clamp arm that is available as an option. To fabricate a clamp arm, make sure that the allowable bending moment and the inertial moment will be within the specified range. If a clamp arm that exceeds the specified value is installed, the internal mechanism in the cylinder could become damaged. Ensuring Safety q If one side of the piston is pressurized by supplying air with the clamp arm attached, the piston will move vertically while the clamp arm rotates. This operation could be hazardous to personnel, as their hands or feet could get caught by the clamp arm, or could lead to equipment damage. Therefore, it is important to secure as a danger zone a cylindrical area with the length of the clamp arm as its radius, and the stroke plus mm as its height. Installation and djustment/ egarding lamp rm emoval and einstallation q uring the removal or reinstallation of the clamp arm, make sure to use a wrench or a vise to secure the clamp arm before removing or tightening the bolt. This is to prevent the bolt tightening torque from being applied to the piston rod, which could damage the cylinder's internal mechanism. Mounting bolt for MK Mounting method: through hole mounting bolt is available. ow to order: Suffix (MK) to the size of bolts to be used. Example) M5 X 5l (MK) Mounting bolt Precautions for esigning and Mounting rms When arms are to be made separately, their length and weight should be within the following range. 1. llowable bending moment Use the arm length and operating pressure within graph 1 for allowable bending moment loaded piston rod. Graph 1 2. Moment of inertia When the arm is long and heavy, damage of internal parts may be caused due to inertia. Use the inertia moment and cylinder speed within graph 2 based on arm requirements. Graph 2 When arm length is cm, pressure should be less than MK /:.45MPa MK /:.55MPa MK 5/:.MPa When arm's inertia is 3 X 1 4 kg m 2, cylinder speed should be less than MK /: 5mm/s MK /: 15mm/s efer to p for calculating moment of inertia.
