5. Installation
5.3 Installing the Main Body
Mount the actuator to a machined surface or one of the flat surfaces of comparable precision.
The side faces and lower surface of the base run parallel with the guides. When traveling precision is required,
use these as the reference planes for mounting.
5.3.1 Using the Tapped Holes at Back of the Base (All Types)
Tapped holes are provided on the back of the base for
mounting the actuator. Install the actuator using these
tapped holes. The effective depths of base mounting screws
are listed below. Be careful not to let the ends of bolts project
from the holes. If necessary, use the additional reamed holes
that are provided for positioning purposes.
Type Tap Size Screw Effective Depth Reamed Hole
