*1 The lock holding force of the CLKQ□ is 982 N. Design the circuit such that the lock holding force is taken into consideration when the operating pressure exceeds 0.75 MPa. The operating pressure should not be greater than the lock holding force as it may cause wearing out and/or damage of the locking part and shorten the lock life and may lead to possible failure if applied with a load larger than the lock holding force.
*2 It takes approximately 0.3 seconds for the cylinder to operate to generate clamping force from an unclamping state (when no speed controller is installed). Design the circuit taking into consideration the time before the clamping force is generated.
*3 Determine the clamping force according to the strength of the workpiece. It can be damaged if the clamping force is too large.

Precautions

Caution on Design

  • *There is a possibility of dangerous sudden action by cylinders if sliding parts of machinery are twisted due to external forces, etc.
    In such cases, human injury may occur; e.g. by catching hands or feet in the machinery, or damage to the machinery itself may occur. Therefore, the machine should be adjusted to operate smoothly and designed to avoid such dangers.
  • *A protective cover is recommended to minimize the risk of personal injury.
    If a stationary object and moving parts of a cylinder are in close proximity, personal injury may occur. Design the structure to avoid contact with the human body.
  • *Securely tighten all stationary parts and connected parts so that they will not become loose.
    Especially when a cylinder operates with high frequency or is installed where there is a lot of vibration, ensure that all parts remain secure.
  • *Design the equipment so that the maximum theoretical force is not applied to the cylinder.
    If the cylinder becomes damaged there is a danger of human injury and/or equipment damage.
  • *Select the mounting base by taking into consideration its rigidity because the cylinder applies a large amount of force.
    Otherwise there is a danger of human injury and/or equipment damage.
  • *Consider the possibility of a decrease in circuit pressure when power is turned off.
    If the cylinder is used for a clamping application there is a danger of the workpiece being released since the circuit pressure decreases when the power is turned off. Install safety equipment to prevent human injury and damage to machine and/or equipment. The same consideration should be given for hanging or lift applications to prevent dropping of a workpiece.
  • *Consider a possible loss of power source.
    Measures should be taken to protect against bodily injury and equipment damage in the event that there is a loss of power to equipment controlled by pneumatics, electricity or hydraulics.
  • *Consider emergency stops.
    Design so that human injury and/or damage to machinery and equipment will not be caused when machinery is stopped by a safety device under abnormal conditions, a power outage or a manual emergency stop.
  • *Consider the action when operation is restarted after an emergency stop or abnormal stop.
    Design the machinery so that human injury or equipment damage will not occur upon restart of operation. When the cylinder has to be reset at the starting position, install manual safety equipment.
  • *Intermediate stop
    In the case of the 3-position closed center of a valve, it is difficult to make a piston stop at the required position as accurately and precisely as with hydraulic pressure due to compressibility of air. Furthermore, since valves and cylinders, etc., are not guaranteed for zero air leakage, it may not be possible to hold a stopped position for an extended period of time. Contact the manufacturer's support center if it is necessary to hold a stopped position for an extended period. Do not intermediately stop the CLKQ cylinder during a locking operation because it will shorten the life of the cylinder.

Other precautions

  • *Be sure to read the safety precautions and individual product precautions before use.
  • *The photos show representative examples of the series. This product's specifications may differ.
  • *See the manufacturer's catalog for product information other than the above.
