Refer to each graphregarding the maximum allowable moment and maximum allowable load for a particular piston speed.We recommend installing an external shock absorber when the cylinder is combined withanother guide (connection with floating bracket, etc.) and the maximum allowable load isexceeded, or when the operating speed is 1000 to 1500 mm/s for bore sizes ø16, ø50, ø63, ø80and ø100.Maximum Allowable MomentSelect the moment from within the rangeof operating limits shown in the graphs.Note that the maximum allowable loadvalue may sometimes be exceededeven within the operating limits shown inthe graphs. Therefore, also check theallowable load for the selectedconditions.Moment (N·m)m2m3F1M1=F1 x L1F2M2=F2 x L2F3M3=F3 x L3L1L21. Maximum allowable load (1), static moment (2), and dynamic moment (3) (at the time of impact withstopper) must be examined for the selection calculations.∗ To evaluate, use υa (average speed) for (1) and (2), and υ (collision speed υ = 1.4 υa) for (3). Calculate mmaxfor (1) from the maximum allowable load graph (m1, m2, m3) and Mmax for (2) and (3) from the maximum allowablemoment graph (M1, M2, M3).Sum of guideload factorsΣα = + + ≤1Load mass [m]Maximum allowable load [mmax]L3Static moment [M] (1)Allowable static moment [Mmax]Dynamic moment [ME] (2)Allowable dynamic moment [MEmax]Maximum Load MassSelect the load from within the range oflimits shown in the graphs.

When this happens, the sum of theload factors (Σα) is the total of all such moments.2.

Mechanically Jointed Rodless CylinderBasic TypeSeries <strong>MY1B</strong>Cushion CapacityCushion SelectionAbsorption Capacity of Rubber Bumper, Air Cushion and Stroke Adjusting UnitsRubber bumpers are a standard feature on<strong>MY1B</strong>10.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. Securethe adjusting bolt at the position whereit protrudes approximately 0.5 mm fromthe shock absorber.Adjusting boltShock absorber0.52.

(Except ø10)For other lengths, please consult with<strong>SMC</strong> (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.

Series MY1MCushion 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 such acase, 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.

Refer to each graphregarding the maximum allowable moment and maximum allowable load for a particular piston speed.Maximum Allowable MomentSelect the moment from within therange of operating limits shown in thegraphs.

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 factorsΣα = + + ≤ 1Load mass [m]Maximum allowable load [m max]Static moment [M] (1)Allowable static moment [Mmax]Dynamic moment [ME] (2)Allowable dynamic moment [MEmax]Note 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.Maximum Load MassSelect the load from within the rangeof limits shown in the graphs. Notethat the maximum allowable momentvalue may sometimes be exceededeven within the operating limits shownin the graphs. Therefore, also checkthe allowable moment for the selectedconditions.2.

Series MY1CCushion 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.Adjusting boltAbsorption Capacity of Air Cushion and Stroke Adjusting UnitsMY1C16Collision speed mm/sMY1C20Collision speed mm/s Collision speed mm/s200015001000500400300200200015001000500400300200100MY1C322000150010005004003002001002 3 4 5 10 20 30MY1C402000150010005004003002001002 3 4 5 10 20 50MY1C25 Horizontal collision: P = 0.5 MPa MY1C50 Horizontal collision: P = 0.5 MPa200015001000500400300200Horizontal collision: P = 0.5 MPa1000.5 1 2 3 4 5 10 20 30m3 max. m2 max. m1 max.Horizontal collision: P = 0.5 MPa1 2 3 4 5 10 20 30 40 50m3 max.L unitAir cushionm2 max.L unitAir cushionH unitL unitH unitAir cushionm1 max.Collision speed mm/s200015001000500400300200Horizontal collision: P = 0.5 MPam3 max.m3 max.Air cushionLoad mass kg Load mass kgCollision speed mm/sLoad mass kg Load mass kgCollision speed mm/sH unitL unitm2 max. m1 max.L unitAir cushionm2 max. m1 max.H unitAir cushion40 50H unitL unit100Horizontal collision: P = 0.5 MPa0.51001 2 3 4 5 10 20 30 40 501002 3 4 5 10 20 30 40 50100m3 max. m2 max.Load mass kgm1 max.m3 max.Load massm2 max.kgm1 max.Shock 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. When this happens, the sumof the load factors (∑α) is the total of all such moments.m: Load mass (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 mass [m]Maximum allowable load [m max]·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 coefficientWith rubber bumper = 4/100(<strong>MY1B</strong>10, 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 CylinderLinear Guide TypeSeries MY1HCushion 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.

Series MY1HSpecific Product Precautions 1Be sure to read before handling.Refer to front matters 54 and 55 for Safety Instructions and pages 3 to 11 for Actuatorand Auto Switch Precautions.CautionUse caution not to get your hands caught in the unit.• When using a product with stroke adjusting unit, the spacebetween the slide table (slider) and the stroke adjusting unitbecomes narrow at the stroke end, causing a danger of handsgetting caught. Install a protective cover to prevent direct contactwith the human body.Adjusting boltlock nutCautionUnit holding boltShock absorberThe unit can be secured by evenly tightening the four unit holdingbolts.Do 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 <strong>SMC</strong> (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.

(Thenotches are found in alternating increments of 5 mm and 10mm.)3. Tighten the holding screw to 0.3 N·m. Make sure that thetightening does not cause excessive torque.The fixture fits into the fastening hole in the guide rail to preventslippage, which enables fastening with low torque.4. Tighten the lock nut to 0.6 N·m.5. Make fine adjustments with the adjusting bolt and shockabsorber.<strong>MY1B</strong>MY1MMY1CMY1HMY1HTMY1WMY2CMY2HMY3AMY3BMY3MD-1025-XIndividual-XTechnicaldata


Series MY1HSpecific Product Precautions 2Be sure to read before handling.Refer to front matters 54 and 55 for Safety Instructions and pages 3 to 11 for Actuatorand Auto Switch Precautions.With End LocksRecommended Pneumatic CircuitCautionThis is necessary forthe correct locking andunlocking actions.CautionCautionCautionOperating Precautions1. 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 Pressure1. 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.1026CautionRelation to Cushion1. 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.Adjusting the End Lock MechanismCaution1. 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.Lock finger(Hole)Lock pistonStroke adjusting unitWarningCautionReleasing the LockManual ReleasebScrewdriver, etc.aLock fingerLock fingerholding bolt1. 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.1. 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.Other handling precautionsregarding mounting,piping, and environmentare the same asthe standard series.

Series MY1Specific Product Precautions 1Be sure to read before handling.Refer to front matters 54 and 55 for Safety Instructions and pages 3 to 11 for Actuatorand Auto Switch Precautions.SelectionCaution1. When using a cylinder with long strokes, implementan intermediate support.When using a cylinder with long strokes, implement anintermediate support to prevent the tube from sagging andbeing deflected by vibration or an external load.Refer to the Guide for Side Support Application on pages 971,993, 1013, 1037 and 1050.2.For intermediate stops, use a dual-side pressurecontrol circuit.Since the mechanically jointed rodless cylinders have aunique seal structure, slight external leakage may occur.Controlling intermediate stops with a 3 position valve cannothold the stopping position of the slide table (slider). Thespeed at the restarting state also may not be controllable. Usethe dual-side pressure control circuit with a PAB-connected 3position valve for intermediate stops.3. Constant speed.Since the mechanically jointed rodless cylinders have aunique seal structure, a slight speed change may occur. Forapplications that require constant speed, select an applicableequipment for the level of demand.4. Load factor of 0.5 or lessWhen the load factor is high against the cylinder output, itmay adversely affect the cylinder (condensation, etc.) andcause malfunctions. Select a cylinder to make the load factorless than 0.5. (Mainly when using an external guide)5. Cautions on less frequent operationWhen the cylinder is used extremely infrequently, operationmay be interrupted in order for anchoring and a changelubrication to be performed or service life may be reduced.6. Consider uncalculated loads such as piping,cableveyor, etc., when selecting a load momentCalculation does not include the external acting force ofpiping, cableveyor, etc. Select load factors taking into accountthe external acting force of piping, cableveyor, etc.7. AccuracyThe mechanical jointed rodless cylinder does not guaranteetraveling parallelism. When accuracy in traveling parallelismand a middle position of stroke is required, please consult<strong>SMC</strong>.CautionHead coverSlide tableHead coverMounting2. When connecting to a load which has an externalguide mechanism, use a discrepancy absorptionmechanism.• Mechanically jointed rodless cylinders can be used with adirect load within the allowable range for each type of guide.Please note that careful alignment is necessary whenconnecting to a load having an external guide mechanism.Mount the external guide mounting brackets and floatingbrackets in a place where the required degree of freedom forthe floating Y and Z axes can be secured.The thrust transmission area of the floating bracket must befixed so that it does not partially contact the body.∗ Refer to the Coordinates and Moment in Model Selection onpage 947 for the details of floating Y and Z axes.3. Do not mount cylinders as they are twisted.When mounting, be sure for a cylinder tube not to be twisted.The flatness of the mounting surface is not appropriate, thecylinder tube is twisted, which may cause air leakage due tothe detachment of a seal belt, damage a dust seal band, andcause malfunctions.4. Do not mount a slide table on the fixed equipmentsurface.It may cause damage or malfunctions since an excessive loadis applied to the bearing.Cylinder tubeMounting with a slide table (slider)5. Consult <strong>SMC</strong> when mounting in a cantilevered way.Since the cylinder body deflects, it may cause malfunctions.Please consult <strong>SMC</strong> when using it this way.Slide tableCylinder tubeMounting in a cantilevered wayCautionMounting1. Do not apply strong impacts or excessive momentto the slide table (slider).• The slide table (slider) is supported by precision bearings(MY1C, MY1H) or resin bearings. Therefore, do not applystrong impacts or excessive moment, etc., when mountingworkpieces.6. Fixed parts of the cylinder on both ends must haveat least 5 mm of contact between where the bottomof the cylinder tube and the equipment surface.Head coverSlide tableCylinder tube5 mm or more 5 mm or more1054


Series MY1Specific Product Precautions 2Be sure to read before handling.Refer to front matters 54 and 55 for Safety Instructions and pages 3 to 11 for Actuatorand Auto Switch Precautions.CautionMounting7. Do not generate negative pressure in the cylindertube.Take precautions under operating conditions in whichnegative pressure is generated inside the cylinder by externalforces or inertial forces. Air leakage may occur due toseparation of the seal belt. Do not generate negative pressurein the cylinder by forcibly moving it with an external forceduring the trial operation or dropping it with self-weight underthe non-pressure state, etc. When the negative pressure isgenerated, slowly move the cylinder by hand and move thestroke back and forth. After doing so, if air leakage stilloccurs, please consult <strong>SMC</strong>.CautionHandling1. Do not unnecessarily alter the guide adjustmentsetting.• The adjustment of the guide is preset and does not requirereadjustment under normal operating conditions. Therefore,do not unnecessarily alter the guide adjustment setting.However, series other than the MY1H Series can bereadjusted and their bearings can be replaced.To perform these operations, refer to the bearingreplacement procedure given in the instruction manual.2. Do not get your hands caught during cylinderoperation.For the cylinder with a stroke adjusting unit, the spacebetween the slide table and stroke adjusting unit is very small,and your hands may get caught. When operating without aprotective cover, be careful not to get your hands caught.3. Avoid operation that causes negative pressureinside the cylinder.Take precautions under operating conditions in whichnegative pressure is increased inside the cylinder by externalforces or inertial forces. Air leakage may occur due toseparation of the seal belt.WarningService Life and Replacement Period of Shock AbsorberCautionOperating Environment1. Do not use in an environment where the cylinder isexposed to coolant, cutting oil, water drops, adhesiveforeign parti-cles, dust, etc. and avoid use withcompressed air containing drainage and foreignparticles.• Foreign matter or liquids on the cylinder , s interior orexterior can wash out the lubricating grease, which can leadto deterioration and damage of dust seal band and sealmaterials, causing a danger of malfunction.When operating in locations with exposure to water and oil,or in dusty locations, provide protection such as a cover toprevent direct contact with the cylinder, or mount so that thedust seal band surface faces downward, and operate withclean compressed air.2. Carry out cleaning and grease application suitablefor the operating environment.Carry out cleaning regularly when using in an operatingenvironment in which the product is likely to get dirty.After cleaning, be sure to apply grease to the top side of thecylinder tube and the rotating part of the dust seal band.Apply grease to these parts regularly even if not aftercleaning. Please consult <strong>SMC</strong> for the cleaning of the slidetable (slider) interior and grease application.1.
