Series MY18PrecautionsBe sure to read before handling. For Safety Instructions and Actuator Precautions, refer to pages 8-34-3 to 8-34-6.MountingCaution1. Do not apply strong impacts orexcessive moment to the slidetable (slider).• The slide table (slider) is supported byprecision bearings (MY1C, MY1H) orresin bearings (MY1B, MY1M).Therefore, do not apply strongimpacts or excessive moment, etc.,when mounting workpieces.2. Align carefully when connectingto a load having an externalguide mechanism.• Mechanically jointed rodless cylinderscan be used with a direct load withinthe allowable range for each type ofguide. Please note that carefulalignment is necessary whenconnecting to a load having anexternal guide mechanism. As thestroke becomes longer, variations inthe center axis become larger.Consider using a connection method(floating mechanism) that is able toabsorb these variations. Furthermore,use the special floating brackets (referto page 8-11-28) which have beenprovided for Series MY1B.3. Do not use in an environmentwhere the cylinder is exposedto coolant, cutting oil, waterdrops, adhesive foreign particles,dust, etc. and avoid usewith compressed air containingdrainage and foreign particles.•Foreign matter or liquids on thecylinder , s interior or exterior can washout the lubricating grease, which canlead to deterioration and damage ofdust seal band and seal materials,causing a danger of malfunction.When operating in locations withexposure to water and oil, or in dustylocations, provide protection such as acover to prevent direct contact withthe cylinder, or mount so that the dustseal band surface faces downward,and operate with clean compressedair.Caution1. Do not unnecessarily alter theguide adjustment setting.• The adjustment of the guide is presetand does not require readjustmentunder normal operating conditions.Therefore, do not unnecessarily alterthe guide adjustment setting.However, series other than the MY1HSeries can be readjusted and theirbearings can be replaced.To perform these operations, refer tothe bearing replacement proceduregiven in the instruction manual.Caution1. Air leakage•Take precautions under operatingconditions in which negativepressure is increased inside thecylinder by external forces or inertialforces. Air leakage may occur due toseparation of the seal belt.8-11-8

Mechanically Jointed Rodless CylinderBasic TypeSeries MY1B18Cushion CapacityCushion SelectionRubber bumpers are a standard feature onMY1B10.Since the stroke absorption of rubber bumpersis short, when adjusting the stroke withan A unit, install an external shock absorber.The load and speed range which can beabsorbed by a rubber bumper is inside therubber bumper limit line of the graph.Air cushions are a standard feature onmechanically jointed rodless cylinders.(Except ø10.)The air cushion mechanism is incorporatedto prevent excessive impact of the pistonat the stroke end during high speedoperation. The purpose of air cushion,thus, is not to decelerate the pistonnear the stroke end.The ranges of load and speed that aircushions can absorb are within the aircushion limit lines shown in the graphs.Use this unit when operating with a load orspeed exceeding the air cushion limit line,or when cushioning is required outside ofthe effective air cushion stroke range dueto stroke adjustment.L unitUse this unit when cushioning is necessaryoutside of the effective air cushionrange even if the load and speed are withinthe air cushion limit line, or when the cylinderis operated in a load and speedrange above the air cushion limit line andbelow the L unit limit line.H unitUse this unit when the cylinder is operatedin a load and speed range above the L unitlimit line and below the H unit limit line.Caution1. Refer to the figure below whenusing the adjusting bolt to performstroke adjustment.When the effective stroke of the shockabsorber decreases as a result ofstroke adjustment, the absorption capacitydecreases dramatically.

Install a protective coverto prevent direct contact with the humanbody.Adjusting boltlock nutLock plateThe unit can be secured by evenlytightening the four unit holding bolts.CautionUnit holding boltLock plateholding boltShock absorberDo not operate with the strokeadjusting unit fixed in anintermediate position.When the stroke adjusting unit is fixed inan intermediate position, slippage canoccur depending on the amount of energyreleased at the time of an impact. In suchcases, the use of the adjusting boltmounting brackets, available per made-toorderspecifications -X416 and -X417, isrecommended. (Except ø10)For other lengths, please consult withSMC (Refer to “Tightening Torque forStroke Adjusting Unit Holding Bolts”.)Loosen the adjusting bolt lock nut, andadjust the stroke from the lock plate sideusing a hexagon wrench. Retighten thelock nut.Loosen the two lock plate holding bolts,turn the shock absorber and adjust thestroke. Then, uniformly tighten the lockplate holding bolts to secure the shockabsorber.Take care not to over-tighten the holdingbolts. (Except ø10 and ø20 L unit.) (Referto “Tightening Torque for Stroke AdjustingUnit Lock Plate Holding Bolts”.)Note)Although the lock plate may slightly benddue to tightening of the lock plate holdingbolt, this does not a affect the shockabsorber and locking function.

In such a case, use a sidesupport in the middle section. The spacing (l)of the support must be no more than thevalues shown in the graph on the right.ml(kg) 200190180170160150(4000)140Caution1. If the cylinder mounting surfaces arenot measured accurately, using a sidesupport may cause poor operation.Therefore, be sure to level the cylindertube when mounting. Also, for longstroke operation involving vibrationand impact, use of a side support isrecommended even if the spacingvalue is within the allowable limitsshown in the graph.2.

Maximum allowable load (1), static moment (2), and dynamic moment (3) (at the time ofimpact with stopper) must be examined for the selection calculations.∗ To evaluate, use υa (average speed) for (1) and (2), and υ (collision speed υ = 1.4υa)for (3). Calculate mmax for (1) from the maximum allowable load graph (m1, m2, m3) andMmax for (2) and (3) from the maximum allowable moment graph (M1, M2, M3).Sum of guideload factorsNote 1) Moment caused by the load, etc., with cylinder in resting condition.Note 2) Moment caused by the impact load equivalent at the stroke end (at the time of impact with stopper).Note 3) Depending on the shape of the workpiece, multiple moments may occur. When this happens, the sumof the load factors (∑α) is the total of all such moments.m: Load weight (kg)F: Load (N)FE: Load equivalent to impact (at impact with stopper) (N)υa: Average speed (mm/s)M: Static moment (N·m)Note 4)υ = 1.4υa (mm/s) FE = 1.4υa·δ·m·g∴ME =13Note 5)Σα = + + ≤1Load weight [m]Maximum allowable load [mmax]·FE·L1 = 4.57υaδmL1 (N·m)Static moment [M] (1)Allowable static moment [Mmax]υ: Collision speed (mm/s)L1: Distance to the load's center of gravity (m)ME: Dynamic moment (N·m)δ : Damper coefficient At collision: υ = 1.4υaWith rubber bumper = 4/100(MY1B10, MY1H10)With air cushion = 1/100With shock absorber = 1/100g: Gravitational acceleration (9.8 m/s 2 )Dynamic moment [ME] (2)Allowable dynamic moment [MEmax]2.

Mechanically Jointed Rodless CylinderSlide Bearing Guide TypeSeries MY1M41Cushion CapacityCushion SelectionAir cushions are a standard feature onmechanically jointed rodless cylinders. Theair cushion mechanism is incorporated toprevent excessive impact of the piston atthe stroke end during high speedoperation. The purpose of air cushion,thus, is not to decelerate the piston nearthe stroke end. The ranges of load andspeed that air cushions can absorb arewithin the air cushion limit lines shown inthe graphs.Use this unit when operating with a load orspeed exceeding the air cushion limit line,or when cushioning is required outside ofthe effective air cushion stroke range dueto stroke adjustment.Use this unit when the cylinder stroke isoutside of the effective air cushion rangeeven if the load and speed are within theair cushion limit line, or when the cylinderis operated in a load and speed rangeabove the air cushion limit line or belowthe L unit limit line.Use this unit when the cylinder is operatedin a load and speed range above the L unitlimit line and below the H unit limit line.Caution1. Refer to the figure below whenusing the adjusting bolt toperform stroke adjustment.When the effective stroke of the shockabsorber decreases as a result of strokeadjustment, the absorption capacitydecreases dramatically.

In suchcases, the use of the adjusting boltmounting brackets, available per made-toorderspecifications -X416 and -X417, isrecommended.For other lengths, please consult with SMC(Refer to “Tightening Torque for StrokeAdjusting Unit Holding Bolts”.)Loosen the adjusting bolt lock nut, andadjust the stroke from the lock plate sideusing a hexagon wrench. Retighten thelock nut.Loosen the two lock plate holding bolts,turn the shock absorber and adjust thestroke. Then, uniformly tighten the lockplate holding bolts to secure the shockabsorber.Take care not to over-tighten the holdingbolts. (Except ø16, ø20, ø50, ø63)(Refer to “Tightening Torgue for StrokeAdjusting Unit Lock Plate Holding Bolts”.)Note) Although the lock plate may slightly benddue to tightening of the lock plate holdingbolt, this does not a affect the shockabsorber and locking function.

Mechanically Jointed Rodless CylinderCam Follower Guide TypeSeries MY1C56Cushion CapacityCushion SelectionAir cushions are a standard feature onmechanically jointed rodless cylinders.The air cushion mechanism isincorporated to prevent excessive impactof the piston at the stroke end during highspeed operation. The purpose of aircushion, thus, is not to decelerate thepiston near the stroke end.The ranges of load and speed that aircushions can absorb are within the aircushion limit lines shown in the graphs.Use this unit when operating with a load orspeed exceeding the air cushion limit line,or when cushioning is necessary becausethe cylinder stroke is outside of theeffective air cushion stroke range due tostroke adjustment.L unitUse this unit when the cylinder stroke isoutside of the effective air cushion rangeeven if the load and speed are within theair cushion limit line, or when the cylinderis operated in a load and speed rangeabove the air cushion limit line or belowthe L unit limit line.H unitUse this unit when the cylinder is operatedin a load and speed range above the L unitlimit line and below the H unit limit line.Caution1. Refer to the figure below when using theadjusting bolt to perform strokeadjustment.When the effective stroke of the shockabsorber decreases as a result of strokeadjustment, the absorption capacitydecreases dramatically. Secure the adjustingbolt at the position where it protrudesapproximately 0.5 mm from the shockabsorber.Absorption Capacity of Air Cushion and Stroke Adjusting UnitsMY1C16 Horizontal collision: P = 0.5 MPa MY1C32Collision speed (mm/s)200015001000500400300200100 0.5 1 2 3 4 5 10 20 30MY1C20Collision speed (mm/s)200015001000500400300200100MY1C25Collision speed (mm/s)200015001000500400300200L unitAir cushionm3max m2max m1maxLoad weight (kg)Horizontal collision: P = 0.5 MPa1 2 3 4 5 10 20 30 40 50m3max m2maxLoad weight (kg)Horizontal collision: P = 0.5 MPaH unitL unitAir cushionH unitL unitAir cushionm1maxCollision speed (mm/s)200015001000500400300200100 2 3 4 5 10 20 30 40 50MY1C40Collision speed (mm/s)200015001000500400300200100 2 3 4 5 10 20 50MY1C50Collision speed (mm/s)200015001000500400300200Horizontal collision: P = 0.5 MPaL unitAir cushionm3max m2maxLoad weight (kg)H unitHorizontal collision: P = 0.5 MPaL unitAir cushionm3max m2max m1maxLoad weight (kg)Horizontal collision: P = 0.5 MPaH unitAir cushionm1maxH unitL unit100MXMTSMYCYMGCXD--X20-DataAdjusting bolt1001 2 3 4 5 10 20 30 40 50100 2 3 4 5 10 20 30 40 501000.5m3max m2maxLoad weight (kg)m1maxm3max m2maxLoad weight (kg)m1max2.

In sucha case, use a side support in the middlesection. The spacing (l ) of the supportmust be no more than the values shownin the graph on the right.Caution1. If the cylinder mounting surfaces arenot measured accurately, using a sidesupport may cause poor operation.Therefore, be sure to level the cylindertube when mounting. Also, for longstroke operation involving vibrationand impact, use of a side support isrecommended even if the spacingvalue is within the allowable limitsshown in the graph.2.

Install a protective cover to prevent direct contactwith the human body.Adjusting boltlock nutUnit holding boltShock absorberThe unit can be secured by evenly tightening the four unit holdingbolts.CautionDo not operate with the stroke adjusting unit fixed inan intermediate position.When the stroke adjusting unit is fixed in an intermediate position,slippage can occur depending on the amount of energy releasedat the time of an impact. In such cases, the use of the adjustingbolt mounting brackets, available per made-to-order specifications-X416 and -X417, is recommended. (Except ø10)For other lengths, please consult with SMC (Refer to “TighteningTorque for Stroke Adjusting Unit Holding Bolts”.)Loosen the adjusting bolt lock nut, and adjust the stroke from thehead cover side using a hexagon wrench. Re-tighten the lock nut.Loosen the two unit holding bolts on the shock absorber side, turnthe shock absorber and adjust the stroke. Then, uniformly tightenthe unit holding bolts to secure the shock absorber.Take care not to over-tighten the holding bolts. (Except ø10, ø16,ø20) (Refer to “Tightening Torgue for Stroke Adjusting UnitHolding Bolts”.)PrecautionsCautionTo adjust the stroke adjusting unit of the MY1H10,follow the step shown below.Fine adjustmentrange 10Guide rail holdingscrew pitch 15Holding screwpitch 10Section A-AFixtureLock nutFixingscrewO-ring(For notch)Guide railholding screwAdjustingboltBodyShockabsorberGuiderailAdjusting Procedure1.

Series MY1H72With End LocksRecommended Pneumatic CircuitCautionThis is necessary forthe correct locking andunlocking actions.Caution1. Do not use 3 position solenoid valves.Avoid use in combination with 3 position solenoid valves(especially closed center metal seal types). If pressure istrapped in the port on the lock mechanism side, the cylindercannot be locked.Furthermore, even after being locked, the lock may be releasedafter some time due to air leaking from the solenoid valve andentering the cylinder.2. Back pressure is required when releasing the lock.Before starting operation, be sure to control the system so thatair is supplied to the side without the lock mechanism (in caseof locks on both ends, the side where the slide table is notlocked) as shown in the figure above. There is a possibility thatthe lock may not be released. (Refer to the section on releasingthe lock.)3. Release the lock when mounting or adjusting the cylinder.If mounting or other work is performed when the cylinder islocked, the lock unit may be damaged.4. Operate at 50% or less of the theoretical output.If the load exceeds 50% of the theoretical output, this maycause problems such as failure of the lock to release, ordamage to the lock unit.5. Do not operate multiple cylinders in synchronization.Avoid applications in which two or more end lock cylinders aresynchronized to move one workpiece, as one of the cylinderlocks may not be able to release when required.6. Use a speed controller with meter-out control.Lock cannot be released occasionally by meter-in control.7. Be sure to operate completely to the cylinder strokeend on the side with the lock.If the cylinder piston does not reach the end of the stroke,locking and unlocking may not be possible. (Refer to thesection on adjusting the end lock mechanism.)Operating PressureCautionCautionOperating Precautions1. Supply air pressure of 0.15 MPa or higher to the port on theside that has the lock mechanism, as it is necessary fordisengaging the lock.Exhaust Speed1. Locking will occur automatically if the pressure applied to theport on the lock mechanism side falls to 0.05 MPa or less. Inthe cases where the piping on the lock mechanism side is longand thin, or the speed controller is separated at some distancefrom the cylinder port, the exhaust speed will be reduced. Takenote that some time may be required for the lock to engage.In addition, clogging of a silencer mounted on the solenoidvalve exhaust port can produce the same effect.8-11-76PrecautionsCaution1. When the air cushion on the lock mechanism side is in a fullyclosed or nearly closed state, there is a possibility that the slidetable will not reach the stroke end, in which case locking willnot occur.CautionWarningCautionRelation to CushionAdjusting the End Lock Mechanism1. The end lock mechanism is adjusted at the time of shipping.Therefore, adjustment for operation at the stroke end isunnecessary.2. Adjust the end lock mechanism after the stroke adjusting unithas been adjusted. The adjusting bolt and shock absorber ofthe stroke adjusting unit must be adjusted and secured first.Locking and unlocking may not occur otherwise.3. Perform fine adjustment of the end lock mechanism as follows.Loosen the lock finger holding bolts, and then adjust by aligningthe center of the lock piston with the center of the lock fingerhole. Secure the lock finger.Stroke adjusting unitLock finger(Hole)Lock pistonReleasing the Lock1. Before releasing the lock, be sure to supply air to the sidewithout the lock mechanism, so that there is no load applied tothe lock mechanism when it is released. (Refer to therecommended pneumatic circuits.) If the lock is released whenthe port on the side without the lock is in an exhaust state, andwith a load applied to the lock unit, the lock unit may besubjected to an excessive force and be damaged.Furthermore, sudden movement of the slide table is verydangerous.Manual ReleaseLock fingerLock fingerholding bolt1. When manually releasing the end lock, be sure torelease the pressure.If it is unlocked while the air pressure still remains, it will lead todamage a workpiece, etc. due to unexpected lurching.2. Perform manual release of the end lock mechanism as follows.Push the lock piston down with a screwdriver, etc., and movethe slide table.(b)(a)Screwdriver, etc.Other handling precautionsregarding mounting,piping, and environmentare the same asthe standard series.

Mechanically Jointed Rodless CylinderHigh Precision Guide TypeSeries MY1H73Cushion CapacityCushion SelectionRubber bumpers are a standard feature onMY1H10.Since the stroke absorption of rubberbumpers is short, when adjusting thestroke with an A unit, install an externalshock absorber.The load and speed range which can beabsorbed by a rubber bumper is inside therubber bumper limit line of the graph.Air cushions are a standard feature onmechanically jointed rodless cylinders.The air cushion mechanism isincorporated to prevent excessive impactof the piston at the stroke end during highspeed operation. The purpose of aircushion, thus, is not to decelerate thepiston near the stroke end.The ranges of load and speed that aircushions can absorb are within the aircushion limit lines shown in the graphs.Use this unit when operating with a load orspeed exceeding the air cushion limit line,or when cushioning is required outside ofthe effective air cushion stroke range dueto stroke adjustment.L unitUse this unit when the cylinder stroke isoutside of the effective air cushion rangeeven if the load and speed are within theair cushion limit line, or when the cylinderis operated in a load and speed rangeabove the air cushion limit line or belowthe L unit limit line.H unitUse this unit when the cylinder is operatedin a load and speed range above the L unitlimit line and below the H unit limit line.Caution1. Refer to the figure below whenusing the adjusting bolt toperform stroke adjustment.When the effective stroke of the shockabsorber decreases as a result of strokeadjustment, the absorption capacitydecreases dramatically. Secure theadjusting bolt at the position where itprotrudes approximately 0.5 mm fromthe shock absorber.Adjusting boltShock absorber2.

Maximum allowable load (1), static moment (2), and dynamic moment (3) (at the time ofimpact with stopper) must be examined for the selection calculations.∗ To evaluate, use υa (average speed) for (1) and (2), and υ (collision speed υ = 1.4υa)for (3). Calculate mmax for (1) from the maximum allowable load graph (m1, m2, m3) andMmax for (2) and (3) from the maximum allowable moment graph (M1, M2, M3).Sum of guideload factorsNote 1) Moment caused by the load, etc., with cylinder in resting condition.Note 2) Moment caused by the impact load equivalent at the stroke end (at the time of impact with stopper).Note 3) Depending on the shape of the workpiece, multiple moments may occur.

Do not apply strong impact or excessive moment tothe slide table (slider).Since the slide table (slider) is supported by precisionbearings, do not subject it to strong impact or excessivemoment when mounting workpieces.2. Perform careful alignment when connecting to aload which has an external guide mechanism.Mechanically jointed rodless cylinders can be used with adirect load within the allowable range for each type of guide,but careful alignment is necessary for connection to a loadwhich has an external guide mechanism. Since fluctuation ofthe center axis increases as the stroke becomes longer, use amethod of connection which can absorb the variations(floating mechanism).3. Do not put hands or fingers inside when the body issuspended.Since the body is heavy, use eye bolts when suspending it.(The eye bolts are not included with the body.)CautionMountingHandling1. Do not unnecessarily alter the guide adjustmentsetting.The guide is preadjusted at the factory so that readjustment isnot required under normal operating conditions. Do notinadvertently move the guide adjusting unit and change thesetting.Caution2. Air leakage will result from negative pressure.Take precautions under operating conditions in which negativepressure is increased inside the cylinder by external forces orinertial forces. Air leakage may occur due to separation of theseal belt.CautionSwitch mounting grooveHandlingMounting of Auto Switch1. Insert the auto switch into the cylinder , s switch mountinggroove, then slide it sideways in the direction shown belowand place it inside the switch spacer (with the spacerpositioned over it).2. Use a flat head watchmakers’ screwdriver to fasten the switch,tightening with a torque of 0.05 to 0.1 N·m. As a rule, it shouldbe turned about 90° past the point at which tightening can befelt.BMP1-032Auto switch8-11-96
