8 Series MY Precautions e sure to read before handling. For Safety Instructions and ctuator Precautions, refer to pages 8-4- to Mounting Caution. Do not apply strong impacts or excessive moment to the slide table (slider). The slide table (slider) is supported by precision bearings (MYC, MY) or resin bearings (MY, MYM). Therefore, do not apply strong impacts or excessive moment, etc., when mounting workpieces.. lign carefully when connecting to a load having an external guide mechanism. Mechanically jointed rodless cylinders can be used with a direct load within the allowable range for each type of guide. Please note that careful alignment is necessary when connecting to a load having an external guide mechanism. s the stroke becomes longer, variations in the center axis become larger. Consider using a connection method (floating mechanism) that is able to absorb these variations. Furthermore, use the special floating brackets (refer to page 8--8) which have been provided for Series MY.. Do not use in an environment where the cylinder is exposed to coolant, cutting oil, water drops, adhesive foreign particles, dust, etc. and avoid use with compressed air containing drainage and foreign particles. 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 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. Caution. Do not unnecessarily alter the guide adjustment setting. The adjustment of the guide is preset and does not require readjustment under normal operating conditions. Therefore, do not unnecessarily alter the guide adjustment setting. owever, series other than the MY Series can be readjusted and their bearings can be replaced. To perform these operations, refer to the bearing replacement procedure given in the instruction manual. Caution. ir leakage Take precautions under operating conditions in which negative pressure is increased inside the cylinder by external forces or inertial forces. ir leakage may occur due to separation of the seal belt. 8--8

Refer to each graph regarding the maximum allowable moment and maximum allowable load for a particular piston speed. Caution on Design 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 ø6, ø, ø6, ø80 and ø00. oad weight (kg) 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. m Moment (N m) m m F M = F x F M = F x F M = F x <Calculation of guide load factor>. Maximum allowable load (), static moment (), and dynamic moment () (at the time of impact with stopper) must be examined for the selection calculations.

19 Mechanically Jointed Rodless Cylinder asic 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 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 ø0.) 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 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 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. Caution. Refer to the figure below when using the to perform stroke adjustment. When the effective stroke of the shock absorber decreases as a result of stroke adjustment, the absorption capacity decreases dramatically.

43 Mechanically Jointed Rodless Cylinder Slide earing Guide Type 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 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 to perform stroke adjustment. When the effective stroke of the shock absorber decreases as a result of stroke adjustment, the absorption capacity decreases dramatically.

59 Mechanically Jointed Rodless Cylinder Cam Follower Guide Type 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 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 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 at the position where it protrudes approximately 0. mm from the shock absorber. bsorption Capacity of ir Cushion and Stroke djusting Units MYC6 orizontal collision: P = 0.

76 Series MY With End ocks Recommended Pneumatic Circuit Caution This is necessary for the correct locking and unlocking actions. Caution. Do not use position solenoid valves. void use in combination with position solenoid valves (especially closed center 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.. ack pressure is required when releasing the lock. efore 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 the cylinder. If mounting or other work is performed when the cylinder is locked, the lock unit may be damaged. 4. 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 synchronized 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. e 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 the end lock mechanism.) Operating Pressure Caution Caution Operating Precautions. 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 Precautions Caution. 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. Caution Warning Caution Relation to Cushion djusting the End ock Mechanism. 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 unit has been adjusted. The and shock absorber of the stroke 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 s, and then adjust by aligning the center of the lock piston with the center of the lock finger hole. Secure the lock finger. Stroke unit ock finger (ole) ock piston Releasing the ock. efore 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. Manual Release ock finger ock finger holding. 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.

77 Mechanically Jointed Rodless Cylinder igh Precision 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 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 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 to perform stroke adjustment. When the effective stroke of the shock absorber decreases as a result of stroke adjustment, the absorption capacity decreases dramatically.

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 workpieces.. 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 center 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 s when suspending it. (The eye s are not included with the body.) Caution Mounting andling. Do not unnecessarily alter the guide adjustment setting. The guide is preadjusted at the factory so that readjustment is not required under normal operating conditions. Do not inadvertently move the guide unit and change the setting. Caution. ir leakage will result from negative pressure. Take precautions under operating conditions in which negative pressure is increased inside the cylinder by external forces or inertial forces. ir leakage may occur due to separation of the seal belt.
