Pneumatic Clean Series

Dual Rod Cylinder 11-CXSL/12-CXSL115Specific Product PrecautionsBe 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.CautionMountingqMake sure that the surface on which the cylinder ismounted is flat (reference value of flatness: 0.05mm orless).Dual rod cylinders can be mounted from 3 directions. Makesure that the surface on which the cylinder is to be mountedis flat (reference value for flatness: 0.05 or less). Otherwise,the accuracy of the piston rod operation may not beachieved, leading to possible malfunction.wRetract the piston rod when mounting the cylinder.Scratches and gouges on the piston rod may lead todamaged bearings and seals, which can cause malfunctionor air leakage.eSecure the plate before mounting the load.If the load is mounted without the plate being secured,particle generation may result from piston rod twisting.CautionPipingqSwitch the plugged ports according to the operatingconditions.Dual rod cylinders have 2 supply ports for each operatingdirection (or 3 supply ports only in case of ø6). Plug theappropriate supply port according to the operating conditions.When the plugged port has been switched, check the seatsurface. In case any small leakage is detected, unplug theport, check the seat surface and reassemble.wChange the plug position of the 12- relief port accordingto the operating conditions.A relief port is provided on each side so change the plugposition according to the operating conditions. After thechange, apply a 0.1MPa pressure from the relief port to verifythat there is no leakage in the plug section. If any smallamount of leakage is detected, remove the plug again,confirm the seat surface and reassemble.eWith 11-, be sure to conduct vacuum suction from bothsides.Vacuum suction from one side is not sufficient. Be sure toconduct vacuum suction from both sides.CautionStroke AdjustmentqAfter adjusting the stroke, be sure to tighten the hexagonnut to prevent it from loosening.Dual rod cylinders have a bolt to adjust 0 to –5mm strokes onthe retracted end (IN).Loosening the hexagon nut makes adjustment easy but makesure to tighten it firmly after adjustment to prevent loosening.wNever operate a cylinder with its bumper bolt removed.If the bumper bolt is removed, the piston will hit the headcover, resulting in damage to the cylinder. Therefore, do notuse the cylinder with its bumper bolt removed.eA bumper at the end of the bumper bolt is replaceable. Incase it is lost or fatigued, order by the following partnumbers.ModelPartnumberNo. of bumpersCXS6/10/15CXS10-34A28747Disassembly and MaintenanceCautionqNever use a cylinder with its plate removed.When removing the hexagon socket head cap screw from theend plate, first secure the piston rod to prevent rotation.However, if the sliding parts of the piston rod are scratchedand gouged, malfunction may occur. If the plate is notrequired for your applications, use the cylinder that does notcome with a plate, available through Made to Order (-X593)on page 53.wWhen disassembling and reassembling the cylinder,contact SMC or refer to the separate instruction manual.WarningCXS20/25CXS20-34A28749qNever use a cylinder with its plate removed.When the cylinder is operated, take extra precautions toavoid having your hand or fingers caught between the plateand housing.1CXS32CXS32-34A2875196
