Gripping force Holding conditions. To lift workpieces vertically, be sure to take into consideration the acceleration rate, air pressure, impact etc., in addition to the mass of the workpieces. Lifting direction Consider the center of gravity of the workpiece to avoid moments being applied the magnet gripper as much as possible. If multiple magnet grippers are used for transferring a workpiece with a large surface area, properly allocate the magnet grippers to maintain balance. Horizontal movement of the magnet gripper may cause sideslip of the workpiece depending on the acceleration or friction coefficient between the pad and workpiece. Therefore, the acceleration rate of the lateral movement must be minimized. Moving direction Use the magnet gripper for horizontal handling. Adequate safety factor needs to be considered for inclined handling or vertical Horizontal handling Inclined handling Basic orientation Vertical handling - 8 - Holding force F [N] Thin workpieces may be deformed during transportation. It is recommended to use multiple magnet grippers for scenarios such as this. Calculate the required holding force.

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 m 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 air grippers. 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). 5-4. Piping Caution 1. Refer to the Fittings and Tubing Precautions (Best Pneumatics) for handling one touch fittings. 2.Before piping, blow air (flush) or clean the piping to remove any cutting chips, cutting oil, dust, etc. - 23 - 5-5. 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. Refer to each construction drawing for information on the materials of air grippers. 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. Do not use in dusty locations or where water, oil, etc., splash on the equipment. 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. 5-6. Lubrication Caution Magnet gripper is lubricating non-lube type. 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 additionally lubricated, be sure to use class 1 turbine oil (with no additives) ISO VG320. Do not use machine oil or spindle oil. Stopping lubrication later on may lead to a malfunction because the new lubricant will displace the original lubricant. Therefore, lubrication must be continued once it has been started. If turbine oil is used, refer to the corresponding Safety Data Sheet (SDS). 6. Maintenance or inspection 6-1. Maintenance or inspection Warning 1. Perform maintenance and inspection according to the procedures indicated in the operation manual. If handled improperly, human injury and/or malfunction or damage of machinery and equipment may occur. 2. 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. 3. Drain flushing Remove drainage from air filters regularly. 4. 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. - 24 - 6-2. Replacement part 1.
