11. Load on the Actuator
• The actual load should not exceed the value specified in the catalog.
• Be sure to align the shaft center of the rod and the moving direction of the load.
• Lateral load may cause damage or breakdown of the actuator.
• If the rod may receive lateral load, provide a guide or other appropriate mechanism to support the
actuator in the moving direction of the load.
• Do not allow the rod (slide shaft) to receive rotational torque.
* Doing so may damage the internal parts.
Tighten the nut at the tip of the rod, while securely holding
the rod using a wrench of size 17 (RA4) or 22 (RA5).
12. Actuators with a Switch (Optional)
On actuators with a switch, the switch is stored inside the actuator body on the motor side.
Do not increase the homing speed beyond the default factory setting.
If the homing speed is increased beyond the default, the switch may be damaged.
