GA 2 x P Caution 1. Do not replace the bushings. The bushings are press-fit. To replace them, they must be replaced together with the cover assembly. 2. To replace a seal, apply grease to the new seal before installing it. If the cylinder is put into operation without applying grease to the seal, it could cause the seal to wear significantly, leading to premature air leakage. 3. Cylinders with o50 or larger bore sizes cannot be disassembled. When disassembling cylinders with bore sizes of o20 through o40, grip the double flat part of either the tube cover or the rod cover with a vise and loosen the other side with a wrench or a monkey wrench etc., and then remove the cover. When retightening, tighten approximately 2 degrees more than the original position. (Cylinders with o50 or larger bore sizes are tightened with a large tightening torque and cannot be disassembled. I f disassembly is required, please contact SMC.) Disassembly/Replacement Warning 1. Do not operate the cushion valve in the fully closed or fully opened state. Using it in the fully closed state will cause the cushion seal to be damaged. Using it in the fully opened state will cause the piston rod assembly or the cover to be damaged. 2. Do not turn the cushion valve the number of rotations shown below or more from its fully closed state. If it is turned the number of rotations shown below or more, the cushion valve may come off and jump out by the air pressure, causing a hazard.

Otherwise, cylinder and seal damage may occur. 4. Use caution regarding the cushion performance in the low-speed range. There may be individual performance and effect variances when used near 50 mm/ s. Please consult with SMC about usage. Handling 5. When a cylinder is operated with one end fixed and other free (basic, flange types), a bending moment may act on the cylinder due to the vibration generated at the stroke end, which can damage the cylinder. In such a case, install a mounting bracket to suppress the vibration of the cylinder body or reduce the piston speed so that the cylinder does not vibrate. Also, use a mounting bracket to suppress vibrations when moving the cylinder body or when a cylinder is operated horizontally and fixed at one end at a high speed and frequency. 6. Do not apply excessive lateral load to the piston rod. Easy checking method Minimum operating pressure after the cylinder is mounted to the equipment (MPa) = Minimum operating pressure of cylinder (MPa) + {Load weight (kg) x 9.8 x Friction coefficient of guide/Sectional area of cylinder (mm2)} If smooth operation is confirmed within the above value, the load on the cylinder is the resistance of the thrust only and it can be judged as having no lateral load. Caution 1. Do not use the air cylinder as an air-hydro cylinder. This may result in oil leak. 2. Install a rod boot without twisting. If the cylinder is installed with its bellows twisted, it could damage the bellows. 3. Tighten clevis bracket mounting bolts with the following proper tightening torque. o20: 1.5 N・m, o25 to 32: 2.9 N・m, o40: 4.9 N・m, o50: 11.8 N・m, o63 to 80: 24.5 N・m, o100: 42.2 N・m Be sure to read this before handling.
