Pneumatic Clean Series

Specific Product Precautions193Be sure to read before handling.Refer to pages 7 to 16 of Front matter for safety instructions and common precautions for clean series andpages 2 to 7 for common precautions for actuators.12-CY1B/CY1R/REA Common PrecautionsCautionq Be careful about rotation of the external slider.Rotation should be controlled by connecting the external sliderto another shaft (linear guide, etc.).w Do not operate with the magnetic coupling out ofposition.In case the magnetic coupling is out of position, push theexternal slider back to the correct position by hand at the endof the stroke (or push the piston slider with air pressure).e Do not apply a lateral load to the external slider.When a load is directly mounted on the cylinder, deviations inalignment of their axial centers cannot be offset and will resultin a lateral load that can cause increase in particle generationand malfunction. Employ a connection method which canabsorb deviations in axial alignment and deflection due to thecylinder's own weight. Figure 1 illustrates a recommendedmounting method.Figure 1Guide rodStopperCaution12-REAq Stroke adjustment is for positional alignment.It is not provided to control the cushioning effect (for smoothstart and soft stop) but to align the stroke end position of thecylinder with the mechanical stopper of other equipment.w Conduct stroke adjustment while pressure is notapplied.Conduct stroke adjustment to ensure safety while pressure isnot applied. Before adjustment, exhaust driving air and takemeasures against residual pressure and dropping.1) Insert a wrench into the hexagon hole of the adjustmentscrew to loosen lock nut A.2) Rotate the adjustment screw to right and left and move thecushion ring holder (stroke end) forward and backward toalign the position with that of the external stopper.3) After the stroke end adjustment is completed, retighten locknut A.Backward Note)ForwardAdjustmentscrewLock nut ACushion ring holderBackward ForwardWrenchNote) Do not move it backward, as it is set to afull stroke at the time of shipment.r Be careful about the allowable load when operatingthe cylinder in the vertical direction.The allowable load weight for vertical operation is indicated inthe model selection method. However, if a load exceeding theallowable value is applied, there is possibility that the magnetcoupling will be uncoupled, causing the load to drop down.When employing this type of application, contact SMCregarding the operating conditions (pressure, load, speed,stroke, frequency, etc.).t Do not scratch or gouge the external surface of thecylinder.It can damage the wear ring, increase particle generation andcause malfunction.y Do not use the cylinder with its body fixed.Be sure to secure both head covers (or end covers in case ofCY1R) before using the cylinder. Operation of the cylinder withits body fixed will damage the wear ring, resulting in increase ofparticle generation or malfunction.CautionRodless cylinder12-CY1Rq Pay attention to the cylinder mounting surface.If there is any clearance between the end covers on both endsand the mounting surfaces, adjust the shim with a spacer forsecure installation.Hexagon hole of adjustment screw Lock nut A tightening torqueModelWidth acrossflats (mm)Model Tightening torque (Nm)12-REA25512-REA25 1.212-REA32512-REA32 1.212-REA40612-REA40 2.112-REA50812-REA50 3.412-REA63812-REA63 3.4e "Throttle" type speed controllers are recommendedfor speed adjustment, as shown in the table below.Recommended speed controllersModelModelElbow type Straight union type In-line type12-REA25 10-AS2201F-01-06-X214 10-AS2301F-01-06-X214 10-AS2001F-06-X21412-REA32 10-AS2201F-02-06-X214 10-AS2301F-02-06-X214 10-AS2001F-06-X21412-REA40 10-AS2201F-02-06-X214 10-AS2301F-02-06-X214 10-AS2001F-06-X21412-REA50 10-AS3201F-02-08-X214 10-AS3301F-02-08-X214 10-AS3001F-08-X21412-REA63 10-AS3201F-02-08-X214 10-AS3301F-02-08-X214 10-AS3001F-08-X214Although speed adjustment is possible with meter-in and meteroutspeed controllers, smooth acceleration and decelerationmay not be achieved. In case the mounting orientation is nothorizontal, a system with a pressure regulating circuit on thelower side is recommended. (It is also effective to shorten startupdelay in rising and for energy conservation.)r Cushion adjustment is not necessary.The fixed cushion mechanism does not required theconventional cushion adjustment.174
