We recommend an external shock absorber be installed when the cylinder is combined with another guide (connection with floating bracket, etc.) and the maximum load weight is exceeded.. 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 0. or less. (Mainly when using an external guide) When using it as a load balancer, please contact SMC sales representatives.. 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.. ccuracy Mechanically jointed rodless cylinders do not guarantee traveling parallelism.

6 Series MYB Specific roduct recautions Be sure to read the below before handling. efer to back cover for Safety Instructions. For ctuator and uto Switch recautions, refer to andling recautions for SMC roducts (M-E0-) and Operation Manual. The Operation Manual can be downloaded from the SMC website, Caution ead cover Slide table Cylinder tube Mounting with a slide table (slider) ead cover 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. efer to the Guide to Side Support pplication on page.. 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 dualside pressure control circuit with a B-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. Do not apply strong impacts or excessive moment to the slide table (slider). when mounting workpieces.. 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.. 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.. Consult SMC when mounting in a cantilevered way. Since the cylinder body deflects, it may cause malfunctions. When using it this way, please contact SMC sales representatives. Caution Slide table Cylinder tube Mounting in a cantilevered way Caution ead cover mm or more Mounting. Fixed parts of the cylinder on both ends must have at least mm of contact between where the bottom of the cylinder tube and the equipment surface. Warning Slide table Cylinder tube mm or more 6. 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. ir leakage may occur due to separation inder by forcibly moving it with an external force during the trial operation or dropping it with its own weight under the nonpressure state, etc. When the negative pressure is generated, slowly move the cylinder by hand and move the stroke back and forth. fter doing so, if air leakage still occurs, please contact SMC sales representatives. Operating Environment. Do not use in an environment where the cylinder is exposed to coolant, cutting oil, water drops, adhesive foreign matter, dust, etc. and avoid use with compressed air containing drainage and foreign matter. r s interior or exterior can wash out the lubricating grease, which can lead to deterioration and damage of dust seal band and seal materials, 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 to prevent direct contact with the cylinder, or mount so that the dust seal band surface faces downward, and operate with clean compressed air.. Carry out cleaning and grease application suitable for the operating environment. Carry out cleaning regularly when using in an operating environment in which the product is likely to get dirty. fter cleaning, be sure to apply grease to the top side of the cylinder tube and the rotating part of the dust seal band. pply cleaning of the slide table (slider) interior and grease application, please contact SMC sales representatives.. This product is not designed to be used in a clean room. If you are considering using it in a clean room, please contact SMC sales representatives.

10 Series MYB Cushion Capacity Cushion Selection <ir cushion> ir cushions are a standard feature on mechanically jointed rodless cylinders. The air cushion mechanism is incorporated to prevent excessive impact of the piston with high kinetic energy at the stroke end. The purpose of air cushion, thus, is not 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 and speed exceeding the air cushion limit line, or when cushioning is required 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. <Fastening of unit> The unit can be secured by evenly tightening the four unit holding bolts. <Stroke adjustment with adjustment bolt> oosen the adjustment bolt lock nut, and adjust the stroke from the lock plate side using a hexagon wrench. etighten the lock nut. <Stroke adjustment with shock absorber> oosen the two lock plate holding bolts, turn the shock absorber and adjust the stroke. Then, uniformly tighten the lock plate holding bolts to secure the shock absorber. Take care not to over-tighten the holding bolts. (efer to the Tightening Torque for Stroke djustment Unit ock late olding Bolts. ) (Note) lthough the lock plate may slightly bend due to tightening of the lock plate holding bolt, this does not a affect the shock absorber and locking function. Caution. Use caution not to get your hands caught in the unit. When using a product with stroke adjustment unit, the space between the slide table (slider) and the stroke adjustment unit becomes narrow at the stroke end, causing a danger of hands getting caught. Install a protective cover to prevent direct contact with the human body. djustment bolt lock nut Unit holding bolt ock plate holding bolt bsorption Capacity of ir Cushion and Stroke djustment Units MYB Collision speed mm/s MYB Collision speed mm/s MYB Collision speed mm/s orizontal collision: = 0.
