2.3.2 Installation
The surface to mount the main unit should be a machined surface or a plane that possesses an
equivalent accuracy and the flatness should be within 0.05mm/m. Also, the platform should have a
structure stiff enough to install the unit so it would not generate vibration or other abnormality.
Also consider enough space necessary for maintenance work such as actuator replacement and
inspection.
On the base there is a datum surface prepared for the attachment oblong holes.
The parallelism of the slider operation to the datum surface is 0.05mm/m or less.
On the back side of the actuator, there are attachment through holes, positioning reamed holes and
oblong holes. For the details of the positions and dimensions, check in the appearance drawings. [Refer
to 5. “External Dimensions”]
When repeatability in re-attaching is required after it is detached, utilize the reamed holes. Please note,
however, that a consideration is necessary such as to use only one point on the motor side of the
reamed holes when a fine-tuning such as perpendicularity is required.
[1] Installation of the Main Unit
This actuator is equipped with through holes on the base for installation from the top.
(Be aware that the through holes size is different for each model. Refer to the figure below and

Avoid stainless steel sheet from getting any dent or scratch caused by dropping a bolt or tool on the
sheet while fixing the unit with bolts.
Brake-equipped type ROBO Cylinder is capable to move the slider by its own.
Connect a controller and move the slider with JOG operation to perform installation.
As the attachment bolt, use hex socket head cap screws described in the table below.
