Order with a part number for each type and bore size. . The seal kit includes a grease pack (10 g). Order with the following part number when only the grease pack is needed. Grease pack part no.: GR-S-010 (10 g) Note) In the case of cylinders with auto switches, magnets are installed in the piston. . The material for o20 and o25 cylinders with auto switches is made of stainless steel.

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 o20 through o40, grip the double flat part of either the head 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 re-tightening, 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. If disassembly is required, please contact SMC.) Construction Set of the nos. !0, !1, !2 Series CG3 374
