Refer to each graph regarding 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 with another guide (connection with floating bracket, etc.) and the maximum allowable load is exceeded, or when the operating speed is 000 to 0 mm/s for bore sizes Ø 6, Ø, Ø 6, Ø 80 and Ø 00. Maximum llowable Moment Select the moment from within the range of operating limits shown in the graphs. Note that the maximum allowable load value may sometimes be exceeded even within the operating limits shown in the graphs. Therefore, also check the allowable load for the selected conditions.

17 Mechanically Jointed Rodless Cylinder Basic Type Series MYB Cushion Capacity Cushion Selection bsorption Capacity of Rubber Bumper, ir Cushion and Stroke djustment Units <Rubber bumper> Rubber bumpers are a standard feature on MYB0. Since the stroke absorption of rubber bumpers is short, when adjusting the stroke with an unit, install an external shock absorber. The load and speed range which can be absorbed by a rubber bumper is inside the rubber bumper limit line of the graph. <ir cushion> ir cushions are a standard feature on mechanically jointed rodless cylinders. (Except Ø 0.) The air cushion mechanism is incorporated to prevent excessive impact of the piston at the stroke end during high speed operation. 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. <Stroke adjustment unit with shock absorber> Use this unit when operating with a load or 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 cyl-inder 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. Caution. Refer to the figure below when using the adjustment bolt to perform stroke adjustment. When the effective stroke of the shock absorber decreases as a result of stroke adjustment, the absorption capacity decreases dramatically. Secure the adjustment bolt at the position where it protrudes approximately 0. mm from the shock absorber. djustment bolt 0.

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 Caution Unit holding bolt ock plate holding bolt Shock absorber <Fastening of unit> The unit can be secured by evenly tightening the four unit holding bolts. Do not operate with the stroke adjustment unit fixed in an intermediate position. When the stroke adjustment unit is fixed in an intermediate position, slippage can occur depending on the amount of energy released at the time of an impact. In such cases, as a stroke adjustment unit with the spacer for intermediate securing is available, it is recommended to use it. (Except Ø 0) For other lengths, please consult with SMC (Refer to Tightening Torque for Stroke djustment Unit olding 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. Retighten 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. (Except Ø 0 and Ø unit.)

42 Series MYM 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 at the stroke end during high speed operation. 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. <Stroke adjustment unit with shock absorber> Use this unit when operating with a load or 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 the cylinder stroke is 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 or 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. Caution. Refer to the figure below when using the adjustment bolt to perform stroke adjustment. When the effective stroke of the shock absorber decreases as a result of stroke adjustment, the absorption capacity decreases dramatically. Secure the adjustment bolt at the position where it protrudes approximately 0. mm from the shock absorber. djustment bolt bsorption Capacity of ir Cushion and Stroke djustment Units MYM6 Collision speed [mm/s] MYM Collision speed [mm/s] MYM Collision speed [mm/s] orizontal collision: P = 0.

Precautions Specific product precautions 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. djusting bolt ock nut ock plate <Fastening of unit> The unit can be secured by evenly tightening the four unit holding bolts. Caution Unit holding bolt ock plate holding bolt Shock absorber Do not operate with the stroke adjustment unit fixed in an intermediate position. When the stroke adjustment unit is fix in an intermediate position, slippage can occur depending on the amount of energy released at the time of an impact. In such cases, as a stroke adjustment unit with the spacer for intermediate securing is available, it is recommended to use it. For other lengths, please consult with SMC (Refer to Tightening Torque for Stroke djusting Unit olding 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. Retighten 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. (Except Ø 6, Ø, Ø, Ø 6) (Refer to Tightening Torgue for Stroke djusting Unit ock Plate 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.

62 Series MYC 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 at the stroke end during high speed operation. 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. <Stroke adjustment unit 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 the cylinder stroke is 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 or 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. Caution. Refer to the figure below when using the adjustment bolt to perform stroke adjustment. When the effective stroke of the shock absorber decreases as a result of stroke adjustment, the absorption capacity decreases dramatically. Secure the adjustment bolt at the position where it protrudes approximately 0. mm from the shock absorber. djustment bolt bsorption Capacity of ir Cushion and Stroke djustment Units MYC6 Collision speed [mm/s] MYC Collision speed [mm/s] Collision speed [mm/s] MYC MYC MYC orizontal collision: P = 0.

When the stroke adjusting unit is fixed in an intermediate position, slippage can occur depending on the amount of energy released at the time of an impact. In such cases, as a stroke adjustment unit with the spacer for intermediate securing is available, it is recommended to use it. For other lengths, please consult with SMC (Refer to Tightening Torque for Stroke djustment Unit olding Bolts.) <Stroke adjustment with adjusting bolt> oosen the adjusting bolt lock nut, and adjust the stroke from the lock plate side using a hexagon wrench. Retighten 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.

81 Mechanically Jointed Rodless Cylinder inear Guide Type Series MY Cushion Capacity Cushion Selection <Rubber bumper> Rubber bumpers are a standard feature on MY0. Since the stroke absorption of rubber bumpers is short, when adjusting the stroke with an unit, install an external shock absorber. The load and speed range which can be absorbed by a rubber bumper is inside the rubber bumper limit line of the graph. <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 at the stroke end during high speed operation. 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. <Stroke adjustment unit with shock absorber> Use this unit when operating with a load or 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 the cylinder stroke is 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 or 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. Caution. Refer to the figure below when using the adjustment bolt to perform stroke adjustment. When the effective stroke of the shock absorber decreases as a result of stroke adjustment, the absorption capacity decreases dramatically. Secure the adjusting bolt at the position where it protrudes approximately 0. mm from the shock absorber. djustment bolt bsorption Capacity of Rubber Bumper, ir cushion and Stroke djustment Units MY0 Collision speed [mm/s] Collision speed [mm/s] Collision speed [mm/s] MY MY orizontal collision: P = 0.

83 Series MY Specific Product Precautions Be sure to read before handling. 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 Caution To adjust the stroke adjustment unit of the MY0, follow the step shown below. djustment bolt Fine adjustment Body range 0 Shock absorber olding screw pitch 0 Fixture ock nut Fixing screw O-ring (For notch) Guide rail Guide rail holding screw Guide rail holding screw pitch Section - Shock absorber lock nut Caution Shock absorber <Fastening of unit> The unit can be secured by evenly tightening the four unit holding bolts. Do not operate with the stroke adjustment unit fixed in an intermediate position. When the stroke adjustment unit is fixed in an intermediate position, slippage can occur depending on the amount of energy released at the time of an impact. In such cases, as a stroke adjustment unit with the spacer for intermediate securing is available, it is recommended to use it. (Except Ø 0) For other lengths, please consult with SMC (Refer to Tightening Torque for Stroke djustment Unit olding Bolts.) <Stroke adjustment with adjustment bolt> oosen the adjustment bolt lock nut, and adjust the stroke from the head cover side using a hexagon wrench. Re-tighten the lock nut. <Stroke adjustment with shock absorber> oosen the shock absorber lock nut, and adjust the stroke by turning the shock absorber. Then, re-tighten the lock nut. djusting Procedure. oosen the two lock nuts, and then loosen the holding screws by turning them approximately two turns.. Move the body to the notch just before the desired stroke. (The notches are found in alternating increments of mm and 0 mm.). Tighten the holding screw to 0. N m. Make sure that the tightening does not cause excessive torque. The fixture fits into the fastening hole in the guide rail to prevent slippage, which enables fastening with low torque.. Tighten the lock nut to 0.6 N m.. Make fine adjustments with the adjustment bolt and shock absorber. 8

84 Series MY Specific Product Precautions Be sure to read before handling. With End ocks Recommended Pneumatic Circuit Caution This is necessary for the correct locking and unlocking actions. Caution Caution Caution Operating Precautions. Do not use position solenoid valves. void use in combination with position solenoid valves (especially closed centre metal seal types). If pressure is trapped in the port on the lock mechanism side, the cylinder cannot be locked. Furthermore, even after being locked, the lock may be released after some time due to air leaking from the solenoid valve and entering the cylinder.. Back pressure is required when releasing the lock. Before starting operation, be sure to control the system so that air is supplied to the side without the lock mechanism (in case of locks on both ends, the side where the slide table is not locked) as shown in the figure above. There is a possibility that the lock may not be released. (Refer to the section on releasing the lock.). Release the lock when mounting or adjusting the cylinder. If mounting or other work is performed when the cylinder is locked, the lock unit may be damaged.. Operate at % or less of the theoretical output. If the load exceeds % of the theoretical output, this may cause problems such as failure of the lock to release, or damage to the lock unit.. Do not operate multiple cylinders in synchronization. void applications in which two or more end lock cylinders are synchronised to move one workpiece, as one of the cylinder locks may not be able to release when required. 6. Use a speed controller with meter-out control. ock cannot be released occasionally by meter-in control. 7. Be sure to operate completely to the cylinder stroke end 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 the section on adjusting the end lock mechanism.) Operating Pressure. Supply air pressure of 0. MPa or higher to the port on the side that has the lock mechanism, as it is necessary for disengaging the lock. Exhaust Speed. ocking will occur automatically if the pressure applied to the port on the lock mechanism side falls to 0.0 MPa or less. In the cases where the piping on the lock mechanism side is long and thin, or the speed controller is separated at some distance from the cylinder port, the exhaust speed will be reduced. Take note that some time may be required for the lock to engage. In addition, clogging of a silencer mounted on the solenoid valve exhaust port can produce the same effect. 8 Caution Relation to Cushion. When the air cushion on the lock mechanism side is in a fully closed or nearly closed state, there is a possibility that the slide table will not reach the stroke end, in which case locking will not occur. djusting the End ock Mechanism Caution. The end lock mechanism is adjusted at the time of shipping. Therefore, adjustment for operation at the stroke end is unnecessary.. djust the end lock mechanism after the stroke adjustment unit has been adjusted. The adjustment bolt and shock absorber of the stroke adjustment unit must be adjusted and secured first. ocking and unlocking may not occur otherwise.. Perform fine adjustment of the end lock mechanism as follows. oosen the lock finger holding bolts, and then adjust by aligning the centre of the lock piston with the centre of the lock finger hole. Secure the lock finger. ock finger (ole) ock piston Stroke adjustment unit Warning Caution Releasing the ock Manual Release b Screwdriver, etc. a ock finger ock finger holding bolt. Before releasing the lock, be sure to supply air to the side without the lock mechanism, so that there is no load applied to the lock mechanism when it is released. (Refer to the recommended pneumatic circuits.) If the lock is released when the port on the side without the lock is in an exhaust state, and with a load applied to the lock unit, the lock unit may be subjected to an excessive force and be damaged. Furthermore, sudden movement of the slide table is very dangerous.. When manually releasing the end lock, be sure to release the pressure. If it is unlocked while the air pressure still remains, it will lead to damage a workpiece, etc. due to unexpected lurching.. Perform manual release of the end lock mechanism as follows. Push the lock piston down with a screwdriver, etc., and move the slide table. Other handling precautions regarding mounting, piping, and environment are the same as the standard series.

Caution Mounting. Do not apply strong impact or excessive moment to 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 work pieces.. Perform careful alignment when connecting to a load which has an external guide mechanism. Mechanically jointed rodless cylinders can be used with a direct load within the allowable range for each type of guide, but careful alignment is necessary for connection to a load which has an external guide mechanism. Since fluctuation of the centre axis increases as the stroke becomes longer, use a method of connection which can absorb the variations (floating mechanism).. Do not put hands or fingers inside when the body is suspended. Since the body is heavy, use eye bolts when suspending it. (The eye bolts are not included with the body.) Caution. ir leakage will result from negative pressure. Under operating conditions which create negative pressure inside the cylinder due to external forces or inertial forces, note that air leakage may occur due to separation of the seal belt. Caution andling uto Switch Mounting Caution andling. Do not inadvertently move the setting of the guide adjustment unit. The guide is already adjusted at the factory, and readjustment is not necessary under normal operating conditions. Therefore, do not inadvertently move the setting of the guide adjustment unit. 0 Switch mounting groove MB uto switch

In such a case, use a side support in the middle section. The spacing () of the support must be no more than the values shown in the graph on the right. W [kg] 0 0 Caution. If the cylinder mounting surfaces are not measured accurately, using a side support may cause poor operation. Therefore, be sure to level the cylinder tube when mounting. lso, for long stroke operation involving vibration and impact, use of a side support is recommended even if the spacing value is within the allowable limits shown in the graph..
