Precautions regarding the rod
● Do not apply radial load or load moment to the rod.
Loads can only be applied in the axial direction matching the rod axis.
● In this case, be sure to use an external guide (such as a linear guide).
● When fastening a nut onto the tip bracket thread, make sure that the rod does
not rotate. Use a wrench to fix the width across flat of the tip bracket with the
rod in the maximum retraction position.
● The static allowable torque and the reference value (initial value) of the rod tip
angular displacement are as follows.

Caution
If torque exceeding the allowable value acts on the rod, the rotation stop inside
the ELECYLINDER may be damaged, preventing normal operation.
When reaction force due to pressing operation acts on the rod as lateral load,
make sure that the torque does not exceed the allowable value.
Exceeding the allowable torque may lead to malfunctions or damage to parts.
When the workpiece center of gravity is on the rod axis during vertical operation,
rotational vibration may be generated by the clearance of the internal
rotation-stopper. Attachment of an external guide is recommended to suppress
such vibration.
