2.3.2 Installing the Main Body
The actuator base has mounting holes. Affix the actuator with M4 hexagon socket-head bolts using
these holes. Use of high strength bolts of ISO-10.9 or higher is recommended.
The length of mounting bolts varies depending on the material of the machine frame.
• Steel frame: M4 × 10
• Aluminum frame: M4 × 15
Reamed positioning pin holes are provided in the back face of the base. Use these holes as necessary.
• Reamed hole: �4H7, depth 5mm or less
[Base seating surface]
The base seating surface was changed and the width was reduced in order to minimize base
deformation caused by the installation surface shape when fixing the actuator with bolts (from August
2010).
The installation dimensions stay the same.
