Moment (N m) M1 = F1 x L1 Load weight (kg) Maximum llowable Moment Select the moment within the limits shown in the graphs below. Note that the maximum payload value in some cases may exceed maximum allowable payload despite being within the limit shown in the graph; therefore, payload on the operating conditions should be checked. /M1 Moment (N m) M2 = F2 x L2 /M2, M3 M3 = F3 x L3 Moment (N m) (How to calculate the load ratio). Consider (1) max. load weight, (2) static moment, (3) dynamic moment (when stopper collides) when calculating the max. allowable moment and load weight. Evaluate (1) and (2) as υa (average speed), and (3) as υ (collision speed υ = 1.4 υa). Calculate (1) (Wmax) from the graph of max. payload (W1, W2, W3) and calculate (2) and (3) (Mmax) from the maximum allowable moment graph (M1, M2, M3). Sum of Load weight [m] Maximum load weight [m max] Note 1) Static moment [M] Static allowable moment [Mmax] Dynamic moment [ME] Note 2) Dynamic allowable moment [MEmax] the load factors = + + 1 Note 1) Moment generated by load, etc. when the cylinder stops.

Maximum Load Weight Select the maximum load weight to be applied within the limits shown in the graph. Note that the maximum allowable moment may in some cases exceed Maximum allowable moment despite being within the limit shown in the graph: therefore, allowable moment on operating conditions should be checked. /W1 Load weight (kg) /W2 Load weight (kg) /W3 Load weight (kg) /W4 Load weight (kg) Caution on Pneumatic Circuit Design Operating pneumatic circuit Horizontal, Lateral mounting Vertical mounting e sure to use the circuit above. Please consult with SMC in case of using other circuits. Solenoid Valve for Driving and raking <Solenoid valve for driving> Horizontal, lateral mounting orientation Use pressure center style valve. Control the operation with a meter-out system. Vertical Use exhaust center style valve (external pilot style or direct operated style). <Solenoid valve for braking> Use the solenoid valve for braking which has the effective area equivalent to the one of solenoid valve for driving. If the effective area is smaller, it may encounter an unexpected sudden slide table movement. ir alance On both above mentioned circuit, the air balance is made by pressurizing to both sides of cylinder on the condition of the intermediate stop. In the case of the vertical orientation, reduce the pressure of the upside by regulator () to keep the balance is not made, it may cause unexpected sudden slide table movements after the intermediate stop operation, once the reverse operation occurs, resulting in compromised accuracy of the cylinder. Caution 1. Even though Hy-rodless cylinder can be loaded within the max. allowable payload, precise alignment is required if connected to a payload which has external support structure. The longer the stroke is, the larger the declination of axis center is. Thus, take the connecting method (floating mechanism) into consideration, so that misalignment could be absorbed prior to operation. 2. Due to factory pre-adjusted guide and brake plate, re-adjustment is not required under normal operating conditions. ccordingly, do not change the setting on adjustment section. 3. Do not operate the cylinder in an environment in which the cylinder will be exposed to cutting chips, dust (paper debris, lint, etc.), spatter or cutting fluid (gas oil, water, warm water, etc.), which could lead to operational problems. Install a solenoid valve for braking as close to the cylinder as possible. If there is a long distance between the cylinder and valve, it may cause fluctuations in the stop accuracy or unexpected sudden slide table movements. <Recommended solenoid valve example> Solenoid valve for driving Solenoid valve for braking Supply Pressure Set the supply pressure at 0. to 0. MPa. If setting at less than 0. MPa, malfunction of the release brake may occur. If line pressure is used directly as supply pressure, any fluctuation in pressure will appear in the form of changes in cylinder characteristics. Therefore, make sure to use a pressure regulator to convert line pressure into supply pressure for the actuating valve and the brake valve. In order to actuate multiple cylinders at once, use a pressure regulator that can handle a large air flow volume and also consider installing a surge tank. Precautions e sure to read before handling. For Safety Instructions and ctuator Precautions, refer to pages 9-19-3 to 9-19-. djustment 4. It is recommended that grease be applied periodically to the sliding portion of the bearing and to the dust seal band to increase their service life.. 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.

Take care not to mark or damage the outside surface of the cylinder tube. This may result in damaged bearings or scraper, which will cause cylinder malfunction. 2. Take care not to apply any loads to the dust proof cover. It can cause a cylinder malfunction. 3. ecause the slider is supported by precision bearings, take care not to apply strong impacts or excessive moments to the table when loading a workpiece.

The holding force is the lock s ability to hold a static load that does not involve vibrations or shocks, after it is locked without a load. Therefore, to use the cylinder near the upper limit of the constant holding force, be aware of the following: Select the cylinder bore size so that the load is less than 0% of the holding force. If slipping occurs when the load is over holding force, the brake shoe will be damaged, and it is possible the holding force will become smaller or the cylinder life shortened.
