Mounting・Installation

2-1. Design/Selection
Warning

1. There is a danger of sudden action by cylinders if the sliding parts of machinery are twisted, etc., or changes in forces occur.
   In such cases, human injury may occur, e.g. by hands or feet getting caught in the machinery, or damage to the machinery itself may occur. Therefore, the machine should be designed to operate smoothly and to avoid such dangers.

2. If there is a chance that the product will pose a hazard to humans, install a protective over.
   If the moving portion of the product will pose a hazard to humans or will damage machinery or equipment, provide a construction that prevents direct contact with those areas.

3. Be certain that the secured portions will not loosen.
   Be certain to adopt a reliable connecting method if the cylinder is used very frequently or if it is used in a location that is exposed to a large amount of vibration.

4. Consider the possibility of a power source related malfunction.
   For equipment that relies on power sources such as compressed air, electricity, or hydraulic pressure, adopt a countermeasure to prevent the equipment from causing a hazard to humans or damage to the equipment in the event of a malfunction.

5. Consider the action of the cylinder in the event of an emergency stop.
   Devise a safe system so that if a person engages the emergency stop or if a safety device is tripped during a system malfunction, such as a power outage, the movement of the cylinder will not cause a hazard to humans or damage the equipment.

6. Avoid synchronized operation using cylinders only.
   Even if multiple pneumatic cylinders are initially set to the same speed, their speeds may vary due to changes in operating conditions. Therefore, avoid designs where a single load is moved by synchronizing multiple cylinder operations.

7. Consider the action of the cylinder when restarting after an emergency stop.
   Devise a safe design so that the restarting of the cylinder will not pose a hazard to humans or damage the equipment. Install manually controlled equipment for safety when the actuator has to be reset to the starting position.

8. Do not disassemble the product or make any modifications, including additional machining.
   Doing so may cause human injury and/or an accident.

9. When a cylinder is used in a clamping, suspending, or lifting mechanism
   There is a danger of workpieces dropping if there is a decrease of thrust due to a drop in
   circuit pressure caused by a power outage, etc. Therefore, safety equipment should be installed to prevent damage to machinery and/or human injury.

Caution

1. Operate the cylinder component parts within a range such that collision damage will not occur at the stroke end.
   If the piston with moment of inertia collides with or stops at the stroke end due to the operating conditions, please consider this when selecting the cylinder and take into
   account the allowable kinetic energy.

2. Use a speed controller to adjust the cylinder drive speed, gradually increasing from a low speed to the desired speed setting.

3. If pressure is applied to the external cylinder parts, there is a possibility that air will get inside the cylinder from the rod seal section. (Example: inside a chamber, etc.)

2-2. Mounting
Warning

1. Operation manual
   Install the product and operate it only after reading the operation manual carefully and understanding its contents. Also, keep the manual in a location where it can be referred to as necessary.

2. Ensure sufficient space for maintenance activities.
   When installing the products, allow access for maintenance and inspection.

3. Precaution for tightening torque of the nut
   Make sure that the mounting nut (for mounting cylinder) and rod end nut (for mounting load) are mounted at the maximum tightening torque or less as shown on page 15.

4. Do not perform additional machining on the product.
   Performing additional machining on the product can result in insufficient strength and cause damage to the product. This can lead to possible human injury or damage to the surrounding equipment.

5. Fixed orifice
   To loosen impact, a fixed orifice is incorporated in the hose nipple. Be sure not to enlarge the inside diameter of this orifice, because if the hole is enlarged, the cylinder operating speed may exceed the allowable speed (500mm/sec at no-load), which will result in an increased impact force to damage the cylinder. In applications where a no-load operating speed of more than 500mm/sec is required, the manufacturer should be consulted.

Caution

1. Be certain to align the rod axis with the load and direction of movement when connecting.
   When not properly aligned, the rod and tube may be twisted, and damage may be caused due to wear on certain areas, such as the inner tube surface, bushings, rod  surface, or seals.

2. When an external guide is used, connect the rod end and the load in such a way that there is no interference at any point within the stroke.

3. Do not scratch or gouge the sliding parts of the cylinder tube, piston rod, etc., by striking or grasping them with other objects.
   If the piston sliding part is scratched by an object due to collision, the cylinder operation will be degraded. Even though the cylinder is operating correctly, the scratch will damage the bushing, which adversely affects the operation. As the cylinder tube I.D. is produced with a precise tolerance, if an object is dropped onto it or the damaged part of the cylinder affects the internal surface during installation, operation failure may occur.

4. Do not use until you can confirm that equipment can operate properly.
   Confirm correct mounting by performing function and leak tests properly after compressed air and power are connected following mounting or repair.

5. Be very careful when handling the product.
   Depending on the handling method, there is a risk that the corners of the product will injure your hands, fingers, etc.

6. Do not use it in such a way that a load could be applied to the piston rod during the retraction. The spring that is built into the cylinder provides only enough force to retract the piston rod. Thus, if a load is applied, the piston rod may not be able to retract to the end of the stroke.

7. Recommended mounting hole dimensions for embedded type
   The recommended mounting hole dimensions for embedded type are shown below.

5. Piping connection to the cylinder
   A hose nipple consists of two parts: a fitting body and a box nut.
   There are two sizes, one is for O.D.4mm / I.D.2.5mm tube and the other is for O.D.6mm /
   I.D.4mm. This nipple fits both nylon tube and urethane tube. Connection process of nylon or urethane tube is as follows.

1. Remove the box nut, pass nylon tube or urethane tube through the nut.
2. Insert the tube into the fitting body.
3. Fasten the nut to the body.

6. When the cylinder direction is switched, select an appropriate solenoid valve for direction control from SMC stock. 3-Port solenoid valve is used for switching the valve.

2-4. Lubrication
Warning
1) Lubricating non-lube type cylinders
These cylinders have been lubricated for life at the factory and can be used without any further lubrication. However, in the event that it is lubricated additionally, be sure to use the following one. Stopping lubrication later may lead to malfunctions because the new lubricant will cancel out the original lubricant. Therefore, lubrication must be continued once it has been started.

2-5. Air supply
Warning

1. Type of fluids
   Please consult with SMC when using the product in applications other than compressed air.

2. When there is a large amount of drainage
   Compressed air containing a large amount of drainage can cause the malfunction of pneumatic equipment. An air dryer or water separator should be installed upstream from filters.

3. Drain flushing
   If condensation in the drain bowl is not emptied on a regular basis, the bowl will overflow and allow the condensation to enter the compressed air lines. This causes the malfunction of pneumatic equipment. If the drain bowl is difficult to check and remove, the installation of a drain bowl with an auto drain option is recommended.
   For compressed air quality, refer to the SMC Best Pneumatics No. 6 catalog.

4. Use clean air.
   Do not use compressed air that contains chemicals, synthetic oils that include organic solvents, salt, corrosive gases, etc., as it can cause damage or malfunction.

Caution

1. When extremely dry air is used as the fluid, degradation of the lubrication properties inside the equipment may occur, resulting in reduced reliability (or reduced service life) of the equipment. Please consult with SMC.

2. Install an air filter.
   Install an air filter upstream near the valve. Select an air filter with a filtration size of 5 μm or smaller.

3. Take measures to ensure air quality, such as by installing an aftercooler, air dryer, or water separator.
   Compressed air that contains a large amount of drainage can cause the malfunction of pneumatic equipment, such as valves. Therefore, take appropriate measures to ensure air quality, such as by providing an aftercooler, air dryer, or water separator.

4. Ensure that the fluid and ambient temperatures are within the specified range.
   If the fluid temperature is 5°C or less, the moisture in the circuit could freeze, causing damage to the seals or equipment malfunction. Therefore, take appropriate measures to prevent freezing.
   For compressed air quality, refer to the SMC Best Pneumatics No. 6 catalog.

5. Precautionary measures against condensation
   Moisture condensation can occur inside pneumatic systems due to a drop in temperatures caused by the piping or operating conditions. This can degrade or wash away grease, resulting in a shortened service life or a malfunction.
   For details, refer to the catalog “Precautionary measures against condensation in a pneumatic system” (CAT.P-E01-11).

2-6. Operating environment
Warning

1. Do not use in an atmosphere containing corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these.
2. Do not expose the product to direct sunlight for an extended period of time.
3. Do not use in a place subject to heavy vibration and/or shock.
4. Do not mount the product in locations where it is exposed to radiant heat.
5. In dusty locations or where water or oil, etc., splash on the equipment, take suitable measures to protect the rod.
6. A decrease in the base oil of grease may be accelerated by the properties of the compressed air used in pneumatic equipment, the external environment, operating conditions, etc., and the resulting drop in lubricating performance may have an effect on the equipment’s service life.

Caution

1. Internal lubricant or the base oil of grease may seep out of the cylinder depending on the operating conditions (an ambient temperature of 40°C or more, pressure retention, low-frequency actuation, etc.). Take great care when a clean environment is required.

2-7. Maintenance
Warning

1. Maintenance work
   If handled improperly, compressed air can be dangerous. Assembly, handling, repair, and element replacement of pneumatic systems should be performed by a knowledgeable and experienced person.

2. Drain flushing
   Remove drainage from air filters regularly.

3. Removal of equipment, and supply/exhaust of compressed air
   Before components are removed, first confirm that measures are in place to prevent workpieces from dropping, run-away equipment, etc. Then, cut off the supply pressure and electric power, and exhaust all compressed air from the system using the residual pressure release function. When machinery is restarted, proceed with caution after confirming that appropriate measures are in place to prevent sudden movement.
