WarningCaution12-CY1BDisassembly and Inspection12-CY1Rq Be careful the magnet has a strong attraction.Take special precautions when the external slider and piston slider are removed from the cylinder tube for maintenance. Themagnets installed on each slider have very strong attraction.q Be careful if a slider is removed in the normal condition, it will directly absorb the piston.When removing either an external slider or piston slider, first force the external slider and the piston slider to go off the position todisable the holding power and then remove them separately. Be careful if they are removed in the normal condition, the magnetswill directly attract each other and will not go apart.w Pay attention to the directions of the external slider and piston slider.The external slider and piston slider of F6 and F10 holding L type have polarity. See the figure below for disassembly andmaintenance. Suction the external slider and piston slider and insert them into thecylinder tube so that they will be positioned properly. Insert only the piston slider byrotating it by 180° in the reverse direction when they are positioned as in figure 3.With wrong directions, the specified holding force cannot be achieved.194ActuatorFigure 2. Correct positioningFigure 3. Positioning with wrong directionsTypical example of ø20 to ø63 with L type holding forcee Never disassemble the magnetic components (piston slider and external slider).It can reduce the holding power and cause malfunction.r The holding power of the magnet can be changed (from H type to L type). Consult SMC in this regard.t In addition to this catalog, refer to the disassembly instructions when replacing a seal or wear ring.Cautiony Apply additional tightening when remounting thehead cover after disassembly.In disassembling, clamp one head cover by applying a vise toits two chamfered surfaces and remove the other cover byapplying a wrench or an adjustable spanner to its twochamfered surfaces. When re-tightening, first apply locktight(No. 542, Red) and rotate further by 3° to 5° from the originalposition before removal.y Special tools are needed for disassembly.FSpecial toolSpecial Tool Part Number ListPart no.CYRZ-VCYRZ-WCYRZ-XCYRZ-YApplicable bore size (mm)6, 10, 15, 2025, 32, 405063Warning12-REAq Do not disassemble the product because it maydamage the air cushion mechanism.Contact SMC if disassembly or an overhaul is required.175
