Pneumatic components Safety precautions Always read this section before starting use. Refer to Intro 71 for general details on the cylinder, and to 78 for details on the cylinder. Round shaped medium bore size cylinder SCM Series Design & Selection 2. Fine speed type SCM-F Either a rubber or air cushion type cushion mechanism is assembled in the cylinder. The air cushion absorbs kinetic energy the piston acquires using air compression, and prevents the piston and cover from colliding at stroke end. The cushion is not used to decelerate the piston near stroke end. The table below shows...

SCM Series Design & Selection (Cause of popping out phenomenon ) Reduce the flow rate to reach a fine speed at the exhaust side in a mater-out circuit. This results in the same pressure level on the both sides immediately after valve switched. The thrust caused by the differential of pressurized area of piston is applied to the PUSH direction and a popping-out of piston rod occurs. When the piston moves, the exhaust pressure rises, causing the piston to decelerate, after which it reaches the set pressure. (Reference of popping out occurrence) When piston rod area X air pressure > load...

SCM Series Installation & Adjustment Shifting the band position Loosen the band fixing screw, shift the switch rail and band along the cylinder tube, and tighten at the specified position. Tightening torque is 0.6 to 0.8 N·m. 1. Common CAUTION Switch rails are glued with industrial adhesive tape. If used in an atmosphere containing inorganic or organic solvents or water vapor, rails may peel off. Main inorganic and organic solvent Inorganic solvent: Sodium hydroxide, hydrochloric acid etc. Organic solvent: Toluene, ethanol, hexane, gasoline, kerosene etc. Remove all oil, water and dust from...

SCM Series The seal washer is used as the stopper bolt seal and cannot be repeatedly adjusted. The cushion has no effect when stroke is adjusted. Strokes are adjusted for 25 mm and 50 mm. When using axial foot mounting style, the axial dimension is the standard type. 4. Fine speed type SCM-F Align the cylinder so that no horizontal load is applied. Adjust so that the cylinder does not twist in relation to the sliding guide. Variation of load or resistance may result in unstable operations. Large differential between static friction and dynamic friction of guide results in unstable...

SCM Series During Use & Maintenance 1. Common CAUTION When disassembling the cylinder, hold the across flats section of the head cover or rod cover with a vise, etc., and use a wrench or an adjustable spanner on the across flats section of the other cover. Loosen and remove the cover. When retightening, retighten from the position set before disassembly. Large torque is required to disassemble and assemble 80 and 100 types. Details are given in disassembly/assembly procedures, so contact with CKD sales representative. After operating locking mechanism manually, always return the manual...
