4. Installation procedure (example)
The installation procedure varies based on the accuracy of component parts of equipment.
•If centering is possible without adjustment of assembled parts due to high accuracy of each part, install in order of the Step 1, Step 2, Step 3-A, and Step 4.
•If centering is not easy because of low-accuracy parts, install in order of the Step 1, Step 2, Step 3-B, and Step 4.
Step 1 Installing a guide rail
1. In order to set the position of the guide rail and mounting plate for actuator,
install positioning pins on the base plate.
Intersect at a right angle
Positioning pin
2. Secure a guide rail using screws while pressing the reference surface of
the guide rail to the positioning pin.

*Check the manufacturer of a guide rail
for the position of the reference surface
of the guide rail.
Step 2 Installing a mounting plate
Secure a mounting plate for actuator using screws after positioning it with the
positioning pins on the base plate.
Provide a mounting plate for actuator with reference to "5. To design movable
plate and mounting plate for actuator."
Positioning pin
Step 3-A Installing a movable plate (If centering is possible without adjustment of assembled parts due to high accuracy of each part)
1. In order to set the position of the movable plate and guide block,
install positioning pins on the movable plate.

Screw shaft
mounting hole
Note Design a screw shaft mounting hole in consideration
of a margin so that stacked tolerances of parts can be
absorbed. Provide a mounting plate for actuator with
reference to "5. To design movable plate and mounting
plate for actuator."
2. Secure the movable plate with screws while pressing the
positioning pins on the movable plate to the reference surface of
the guide block.

*Check the manufacturer of a guide rail for the
position of the reference surface of the guide block.
Step 3-B Installing a movable plate (If centering is not easy because of low-accuracy parts)
3. Install the movable plate by either of the following methods.
•Place the movable plate and mounting plate for actuator
together, and secure with screws so that there is no gap
between them.
•Put a block gauge or similar parts between the movable plate
and mounting plate for actuator, and secure with screws so that
there is no gap.
If there is a gap, reinstall the movable plate.

Block gauge
∗㻌If there is a distance between the movable plate and mounting plate
for actuator, use a block gauge or similar parts.
4. Fit the centering shaft with the pilot of the mounting plate for
actuator, and align the centering shaft with the central axis of the
screw shaft mounting hole on the centering adjustment plate.
5. Slide the movable plate back and forth, and secure the movable
plate and centering adjustment plate with screws after checking
that the movable plate can move smoothly so that the centering
shaft does not contact.
If the movable plate does not move smoothly, adjust axis
misalignment between the centering shaft and the centering
adjustment plate while moving the centering adjustment plate
from right to left or up and down.

Note
•Provide a centering shaft with reference to "6. To
design centering shaft and centering adjustment
plate."
•Design the centering adjustment plate and pilot of
the mounting plate for actuator according to the
centering shaft.
Step 4 Installing the screw shaft and
movable plate
1. Secure a compact linear actuator to the mount plate for actuator with
screws.

DR28 M2.5 0.6 (85)
DR42 M4 1.8 (256)
DR60 M5 5 (710)
2. Push the screw shaft into the actuator body once until the set collar stops,
and then pull it out a little. Adjust the screw shaft length to be pulled out so
that the set collar does not contact the actuator body when the screw shaft
is tightened with tools.
3. Secure the screw shaft with a nut after pass it through the screw shaft hole
on the movable plate. (Secure the DR42 and DR60 with a screw.)

4. Perform test operation to check if there is no place to generate abnormal
noises.
