Refer to each graph regarding the maximum allowable moment and maximum load mass for a particular piston speed. Maximum Allowable Moment Select the moment from within the range of operating limits shown in the graphs. Note that the maximum load mass value may sometimes be exceeded even within the operating limits shown in the graphs. Therefore, also check the allowable load for the selected conditions. oad mass (kg) m m Moment (N m) m F M = F x F M = F x F M = F x <Calculation of guide load factor>. Maximum load mass (), static moment (), and dynamic moment () (at the time of impact with stopper) must be examined for the selection calculations. To evaluate, use υa (average speed) for () and (), and υ (impact speed υ =.υa) for (). Calculate m max for () from the maximum load mass graph (m, m, m) and Mmax for () and () from the maximum allowable moment graph (M, M, M).

10 MY Series Cushion Capacity Cushion Selection <Air cushion> Air cushions are a standard feature on mechanically jointed rodless cylinders. The air cushion mechanism is installed to avoid excessive impact of the piston at the stroke end during high speed operation. The air cushion does not act to decelerate the piston near the stroke end. The ranges of load and speed that air cushions can absorb are within the air cushion limit lines shown in the graphs. < with shock absorber> Use this unit when operating with a load or speed exceeding the air cushion limit line, or when cushioning is necessary because the cylinder stroke is outside of the effective air cushion stroke range due to stroke adjustment. unit Use this unit when cushioning is necessary outside of the effective air cushion range even if the load and speed are within the air cushion limit line, or when the cylinder is operated in a load and speed range above the air cushion limit line and below the unit limit line. unit Use this unit when the cylinder is operated in a load and speed range above the unit limit line and below the unit limit line.

32 MY Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page 0 for Safety Instructions and pages to for Actuator and Auto Switch Precautions. Caution Selection. When using a cylinder with long strokes, implement an intermediate support. When using a cylinder with long strokes, implement an intermediate support to prevent the tube from sagging and being deflected by vibration or an external load. Refer to the Guide for Side Support Application (MYC series) on page 8.. For intermediate stops, use a dual-side pressure control circuit. Since the mechanically jointed rodless cylinders have a unique seal structure, slight external leakage may occur. Controlling intermediate stops with a position valve cannot hold the stopping position of the slide table (slider). The speed at the restarting state also may not be controllable. Use the dual-side pressure control circuit with a PAB-connected position valve for intermediate stops.. Constant speed Since the mechanically jointed rodless cylinders have a unique seal structure, a slight speed change may occur. For applications that require constant speed, select an applicable equipment for the level of demand.. oad factor of 0. or less When the load factor is high against the cylinder output, it may adversely affect the cylinder (condensation, etc.) and cause malfunctions. Select a cylinder to make the load factor less than 0.. (Mainly when using an external guide). Cautions on less frequent operation When the cylinder is used extremely infrequently, operation may be interrupted in order for anchoring and a change lubrication to be performed or service life may be reduced.. Consider uncalculated loads such as piping, cableveyor, etc., when selecting a load moment Calculation does not include the external acting force of piping, cableveyor, etc. Select load factors taking into account the external acting force of piping, cableveyor, etc.. Accuracy The mechanical jointed rodless cylinder does not guarantee traveling parallelism. When accuracy in traveling parallelism and a middle position of stroke is required, please consult with SMC. Mounting Caution. Do not apply a strong impact or moment on the slide table (slider). Since the slide table (slider) is supported by precision bearings, do not subject it to strong impact or excessive moment when mounting workpieces.. When connecting to a load which has an external guide mechanism, use a discrepancy absorption mechanism. A mechanically jointed rodless cylinder can be used with a direct load within the allowable range for each guide type, however, align carefully when connecting to a load with an external guide mechanism.. Attaching and detaching the actuator unit (cylinder) When detaching the actuator unit, remove the four cylinder holding bolts and take the actuator unit off the guide unit. When attaching the actuator unit, insert the slider into the slide table on the guide unit, and tighten the four holding bolts equally. Since loosened holding bolts may cause damage or malfunction, be sure to secure them tightly. Guide unit Slide table Cylinder holding bolt Slider Actuator unit (Cylinder) Refer to pages 8 and 90 for the actuator unit (cylinder) replacement part numbers. 0

33 MY Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page 0 for Safety Instructions and pages to for Actuator and Auto Switch Precautions. Caution. Auto Switch Mounting The MY series can be equipped with auto switches on the top of the actuator unit (cylinder) and on the side of the guide unit, but use caution in the following cases. <Mounting an auto switch on the top of the actuator unit (cylinder)> For auto switches with perpendicular electrical entry, the lead wire may interfere with the workpiece depending on the workpiece mounting type and shape. Be sure to allow a clearance in order to keep the lead wire from interfering with the workpiece. Side: Auto switch installation groove Guide unit Top: Auto switch installation groove Actuator unit. Workpiece Mounting When mounting a magnetic workpiece, the auto switch may stop working due to a loss of magnetic force in the cylinder depending on the mounting position. Allow a clearance of mm or more between the auto switch and workpiece. mm or more Auto switch Workpiece Workpiece Auto switch mm or more. Body Mounting When mounting MYG with stroke adjustment unit from the top, move the stroke adjustment unit and secure the body with the end plate mounting holes. After mounting, return the stroke adjustment unit to the stroke end and secure it again. exagon socket head mounting bolt Mounting 8. 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, the cylinder tube is twisted, which may cause air leakage due to the detachment of a seal belt, damage a dust seal band, and cause malfunctions. 9. Do not mount a slide table on the fixed equipment surface. It may cause damage or malfunctions since an excessive load is applied to the bearing. ead cover Slide table Cylinder tube Mounting with a slide table (slider) 0.Consult with SMC when mounting in a cantilevered way. Since the cylinder body deflects, it may cause malfunctions. Please consult with SMC when using it this way. ead cover Slide table Cylinder tube Mounting in a cantilevered way.

Do not generate negative pressure in the cylinder tube. Take precautions under operating conditions in which negative pressure is generated inside the cylinder by external forces or inertial forces. Air leakage may occur due to separation of the seal belt. Do not generate negative pressure in the cylinder by forcibly moving it with an external force during the trial operation or dropping it with self-weight under the non-pressure state, etc. When the negative pressure is generated, slowly move the cylinder by hand and move the stroke back and forth. After doing so, if air leakage still occurs, please consult with SMC..Consider uncalculated loads such as piping, cableveyor, etc., when selecting a load moment Calculation does not include the external acting force of piping, cableveyor, etc. Select load factors taking into account the external acting force of piping, cableveyor, etc. D- -X Technical Data
