(mm) Action Double acting Operating fluid Proof pressure 1.05MPa Max. operating pressure 0.7MPa Min. operating pressure 0.15MPa Ambient and fluid temperature -10 to 60 deg.C (No freezing) Cushion Rubber bumper at both ends Lubrication Not required. - Page 5 ！ Caution 2) Install an air filter. Install an air filter close to the upstream side of the valve. A filtration degree of 5mm or less should be selected. 3) Install an aftercooler, air dryer or drain catch before the filter and take appropriate measures.

3-2. Operating environment ！ Warning 1) Do not use in environments where there is a danger of corrosion. Refer to the construction drawings regarding cylinder materials. 2) Install a cover over the rod if it is used in an area that is dusty, or in an environment in which water or oil splashes on the cylinder. - Page 7 3) Securely tighten all stationary parts and connected parts so that they will not become loose. When the product operates with high frequency or is installed where there is a lot of vibration, ensure that all parts remain secure. 4) A deceleration circuit or shock absorber etc., may be required. When a driven object is operated at high speed or the load is heavy, the cylinder’s cushion will not be sufficient to absorb the shock.

of individual cylinders, and the change of components over time. Therefore, it is possible to synchronize multiple cylinders for a short period of time by adjusting them with a speed controller. However, the synchronization could fail easily due to changes in various conditions. When the synchronization fails, the difference in position will apply an excessive force to the piston rod. - Page 9 4) Do not use the product until you have verified that the equipment can operate properly. After installation, repair or modification, apply compressed air and power supplies to the equipment and perform appropriate functional and leakage inspections to make sure the equipment is mounted properly.

3-7-3. Minimum mountable stroke for a cylinder with auto switch(es) The auto switches applicable to this cylinder may turn on in the entire stroke or two switches may turn on at the same time if the stroke is 5 or less. Be sure to secure the actual operating distance 4mm or more in order to avoid such errors. -
