Selection/Recommended Pneumatic Circuit/Caution on Handling Caution Caution when Locking Holding force (maximum static load) means the maximum capability of holding a static load that is not accompanied by vibration or impact under the condition that no load is applied. Therefore, it does not refer to a load that cannot be held constantly. When using (selecting) this product, carefully check the following points. . If the piston rod slips because the lock’s holding force has been exceeded, the brake shoe could be damaged, resulting in a reduced holding force or shortened life. . The upper limit of the load that is used under the conditions not associated with the kinetic energy when locking, such as drop prevention must be 35% or less of the holding force. . Do not use the cylinder in the locked state to sustain a load that involves impact. Caution 1. In terms of specific load conditions, this allowable kinetic energy is equivalent to a load of 3.7 kg in mass, and a piston speed of 300 mm/sec. Therefore, if the operating conditions are below these values, there is no need to calculate. 2. Apply the following formula to obtain the kinetic energy of the load. Ek: Kinetic energy of load (J) m: Load mass (kg) υ: Piston speed (m/s) 3. The piston speed will exceed the average speed immediately before locking. To determine the piston speed for the purpose of obtaining the kinetic energy of load, use 1.2 times the average speed as a guide. 4. The relationship between the speed and the load is indicated in the graph below. The area below the line is the allowable kinetic energy range. 5. There is an upper limit to the size of the load that can be sustained. Thus, a horizontally mounted cylinder must be operated below the solid line, and a vertically mounted cylinder must be operated below the dotted line. 1 2 Ek = . mυ2 Series CLJ2 Fine Lock Cylinder Double Acting, Single Rod 709 CLJ2 CLM2 CLG1 CL1 MLGC CNG MNB CNA2 CNS CLS CLQ RLQ MLU MLGP ML1C D-�ｮ -X�ｮ
