4 Series MY Model Selection The following are steps for selecting the MY series which is best suited to your application. Guideline for Tentative Model Selection Guideline for tentative model selection Series Type Note Stroke accuracy Use of external guide Direct loaded Table accuracy MYA Basic short type Generally combined with a separate guide making it, by length, more compact. MYB MYM Basic standard type Slide bearing guide type Generally combined with a separate guide, when stroke accuracy is required. Mounting a work piece directly on the product, when stroke accuracy is required. Most suitable Suitable Usable Not recommended Note ) The table accuracy means the amount of table deflection when a moment is applied. Note ) Travelling parallelism is not guaranteed for this cylinder. Please consult with SMC if the travelling parallelism or stroke intermediate position needs to be precise. Selection Flow Chart When an external guide is used, the selection confirmation of the guide capacity should follow the selection procedure of the external guide. The MY series allow direct load application within the allowable range for the built-in guide. The payload in this case will vary depending on the driving speed and the mounting orientation of the cylinder. Please refer to the flow below and confirm the selection. (For more detailed description of the selection flow, please refer to the instruction manual.) Operating conditions m: oad weight (kg) Mounting V : Speed (mm/s) direction: P : Operating pressure (MPa) Re-examine the operating conditions. Tentative selection of cylinder model MYA: Basic short type MYB: Basic standard type MYM: Slide bearing guide type Select larger cylinder size. Change the guide type. Determination of load weight and allowable moment, NG In case of the MYA and MYB only Select the different guide type. Please refer to the information by the guide manufacturer. NG OK OK Examine the cushioning mechanism at stroke end. Built-in cushion stroke adjustment unit NG External shock absorber NG OK OK Examine the auto switch mounting (model). Model selected If the load factor is high in comparison to cylinder output, this will have a negative affect on the cylinder, and may cause malfunctions. Select the cylinder so that the load factor is less than 0. in comparison to the cylinder output (particularly when using an external guide). The selection calculation has not considered factors such as piping and cable bearings etc. Please calculate and select a load factor that considers external forces such as piping and cable bearing. When using an external cushioning unit, we recommend installing a suitable unit near the load s centre of gravity. It is possible to select all models of mechanically jointed rodless cylinder (the MY series) according to the procedure indicated above. Refer to the separate instruction manual for further explanation, and please consult with SMC regarding any questions.

5 Model Selection Series MY Maximum operating speed Warning Reduction circuits or shock absorbers may be necessary. If the driven object is fast, or the weight is large, the cylinder cushion alone may not be able to absorb the impact. In this case, install a reduction circuit before the cushion, or install an external shock absorber to reduce the impact. Please check the machine s rigidity as well. External shock absorbers must meet the characteristics listed on page. Cylinders may be damaged if shock absorbers that do not have the recommended characteristics are used. ow to mount a load Stroke positioning Shock absorber Maximum operating speed (mm/s) Rubber bumper MYA Cylinder stroke end MYB Air cushion Direct loaded MYM Stroke adjustment unit (Option:, unit) Shock absorber MYM Note ) MYA MYB External stopper External shock Note ) absorber Note ) MYM Note ) Rubber bumper MYA Cylinder stroke end Use of external guide Note ) Air cushion MYB Stroke adjustment unit (Option:, unit) Shock absorber MYB Note ) Note ) External stopper External shock absorber Note ) MYA MYB Note ) Note ) Mechanically jointed rodless cylinders can be used with a direct load within the allowable range for each guide type, however, careful alignment is necessary for connection to a load which has an external guide mechanism. The mounting bracket for the external guide and the floating bracket must be mounted in a position that guarantees freedom of movement to the floating Y and Z axial. Ensure that the floating bracket is set so that the thrust transmission section has even contact. For details on the floating Y and Z axial, refer to the coordinates and moments in the selection method on page. Note ) The shock absorber must meet the conditions mentioned on page 0 and. Note ) As the external shock absorber, a unit with appropriate capacity and features should be installed close to the load centre of gravity.

10 Series MY Specific Product Precautions Be sure to read before handling. Refer to back cover for the Safety Instructions, andling Precautions for SMC Products (M-E0-) and the Operation Manual for Actuators and Auto Switches Precautions. Warning. When applying a load directly, set the design so that all the mounting threads on the slide table s upper surface are used. Parts have been made smaller to achieve a compact size. If only some of the threads are used when mounting the load, the impact that results from the operation may cause extremely concentrated stress or disfiguration and may negatively affect operation. In worst cases the cylinder may be damaged, so please be careful. mm or more Selection Caution. Provide intermediate supports for long stroke cylinders. Provide intermediate supports for cylinders with long strokes to prevent rod damage due to sagging of the rod, deflection of the tube, vibration and external loads. For detailed information, please refer to "Guide for Using Side Support" on pages and 7.. 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.. 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. Mounting Caution. At each end of the cylinder, secure a mounting surface with a mm or longer area that contacts the lower side of the cylinder. mm or more. If the cylinder is mounted on the ceiling or wall under the condition where high load factors or impacts are expected, use side supports, in addition to the fixing bolts on the head cover, to support both ends of the cylinder tube. Caution Mounting. Do not mount a slide table on the fixed equipment surface. ead cover Cylinder tube It may cause damage or malfunctions since an excessive load is applied to the bearing.. Consult with SMC Slide table when mounting in Mounting with a slide table (slider) 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. Do not mount Mounting in a cantilevered way 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.. 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. Warning Operating Environment. Avoid use in environments where a cylinder will come in contact with coolants, cutting oil, droplet of water, adhesive matter, or dust, etc. Also avoid operation with compressed air that contains drainage or foreign matter, etc. Foreign matter or liquids on the cylinder's interior or exterior can wash out the lubricating grease, which can lead to deterioration and damage of the dust seal band and seal materials, causing a danger of malfunction. When operating in locations with exposure to water and oil drops, or in dusty locations, provide protection such as a cover to prevent direct contact with the cylinder, or mount so that the dust seal band surface faces downward, and operate with clean compressed air.. The product is not designed for clean room usage. If clean room usage is considered, please consult with SMC. Side support Side support Front matter 7

If the stroke adjustment unit is fixed at an intermediate position, an error may result depending on the collision energy. In that case, the use of the holder mounting bracket for adjustment is recommended. It is provided with the "-X" or "-X7" made-to-order specification. (Refer to MYB Stroke Adjustment Unit Tightening Torque for Fixing Bolts. ) If the stroke adjustment unit is fixed at an intermediate position, the energy absorption capacity may be different. For this reason, refer to the maximum absorbed energy listed above, and use the adjustment unit within the allowable absorption capacity. 9

In conjunction with the absorption capacity selection, however, also confirm the conditions which make the shock absorber collision impact force to stay within the allowable range in the graph. Use of an external shock absorber with conditions exceeding the allowable range may damage the cylinder. To confirm the collision impact force of the shock absorber, first find the impact force or acceleration under the operating conditions using the selection information or selection software provided by the manufacturer and then, refer to the graph. (The selection should allow a sufficient margin because the value calculated by the selection software involves an error with reference to the actual value.)
