[2] Using the Through Holes on the Top of the Base
There are through holes equipped on the base so the unit can be attached from the top of the base.
Detach the side covers on the sides when installing.
(Remove 4 attachment screws (+) with a Philips screwdriver.)
Attempt not to drop the bolts, tools, etc. on the stainless steel sheet when tightening the bolts. Please
avoid making a dent mark or scratches.
The slider cannot be driven only with ROBO Cylinder itself if it is equipped with a brake.
Detach the motor unit once to move the slider for installation, and put the motor unit back on. [Refer to
4.8 Motor Replacement Process]
Or, connect a controller and have JOG operation to move the slider to perform installation.
Apply the socket head cap bolt indicated of the appropriate length suitable for the platform material.

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.
• For the effective engagement length between the bolt and female thread, provide at least the
applicable value specified below:
Female thread is made of steel material ĺ Same length as the nominal diameter
Female thread is made of aluminum ĺ 1.8 times of nominal diameter
Caution: Be careful when selecting the bolt length. If bolts of inappropriate lengths are used,
actuator mounting strength may become insufficient, or contact with driving parts may
occur, resulting in lower precision or unexpected accidents.
Caution When Attaching Side Covers
Keep the dimension shown below for the opening when attaching the side covers.
Also, have the side covers attached in symmetry to the center line.
