2 Rotation time setting Even a small torque generated by the rotary actuator, due to inertia, can cause damage. Therefore, please control rotation time taking the moment of inertia of the load and kinetic energy into consideration. Further details are given at the end of this data sheet. Rotation speed range If a rotation speed is used slower than 0.3 sec/90 sticking may occur. Model Rotation time (sec/90 ) 10mm actuator 0.03~0.3 0mm actuator 0.03~0.3 30mm actuator 0.0~0.3 Mounting and travel index hen pressure is applied to the side, the shaft will rotate clockwise. hen applied to the side, the shaft will rotate counter-clockwise. Precautions 1. Use clean air.. ubrication is not required. 3. If the kinetic energy of the load exceeds the permissible range, use external stops to absorb load.. Connect the piping after thoroughly flushing it. 5. void using hydraulic fluid. 6. Shaft load: If a static (ie. non-dynamic) load only is applied to the actuator, it is possible to apply the load values shown in the table below. In order to obtain the proper operating conditions, it is recommended that the load need not be applied directly to the shaft. Fr Fs R Model Fr Fs 10mm actuator mm actuator mm actuator Construction on 70 Recommended mounting methods The values given in the above are the maximum values when actuator is not operating (ie. static loading). If your application requires greater load bearing capacity please use other means of support (ie. thrust bearing).

Note: In the 70 (degree) rotation case How to set rotation time Even a small torque generated by the rotary actuator, due to inertia of the load, can cause damage to the shaft and internal parts. Therefore, please set rotation time taking the inertia of the load and kinetic energy into consideration. (The values of kinetic energy in Tables 1 and, and Figure 1 will be very helpful in setting the rotation time.)

Note : For use without internal rubber damper, you should use an actuator for 70 (Figure b) at 90 or by external stopper making use of a single shaft instead of using end of the rotation.

Stop of load movement via external stop Never use a single flat shaft when the external stop has no ability to absorb the shock.. Movement stop by using the single flat shaft and external stop hen the external stop has the ability to absorb the shock, and the load is within the allowable energy limit, the single flat shaft can be used for stopping.
