[Tightening Torque]
Tightening Screws
•
Use hexagonal socket head bolts for the male threads for installing the base.
•
Use of high-tension bolts meeting at least ISO 10.9 is recommended.
•
Have the length of thread engagement approximately 1.8 times of the nominal diameter.
[Precautions for Attachments]
Please note the following caution notes when installing the unit with using the tapped holes on the
side-mounted bracket.
Do not attempt to affix the unit only with the tapped holes on the side-mounted bracket.
Do not apply external force to the main body.
There may be caused vibration due to the operating condition or installation environment, which
may result in operational failures or components malfunction.

Caution: Be careful when selecting the bolt length. If bolts of inappropriate lengths are
used, the damage of the attachment hole and actuator mounting strength may
become insufficient, or contact with driving parts may occur, resulting in lower
precision or unexpected accidents.
