9. Installation
The actuator mounting surface should be machined or otherwise processed to a smooth surface of
equivalent precision.
9.1 Installation of Actuator
This actuator contains installation tap holes which allow it to be secured from the rear.
(Note that tap hole size depends on model. Please see 2, "External Dimensions."
The actuator also contains reamed holes for use with positioning pins.

Tightening screws
x Use hexagonal socket bolts for the male threads used to install the base.
x Use of high-tension bolts meeting at least ISO-10.9 is recommended.
x Ensure at least the applicable value specified below for the effective engagement length between the
bolt and female thread:
Female thread is made of steel material
o Same length as the nominal diameter
If female screws are made of aluminum
o Maximum screw-in depth
Caution: Select bolt length carefully. Using a bolt with inappropriate length can damage tap holes,
result in insecure installation of actuator, interfere with the operation of the drive section,
reduce the precision of the device, and cause unexpected accidents.
