• There are tapped holes on the slider top for the load attachment. Also, there are two reamed
holes. Utilize the reamed holes when repeatability in the attachment after detaching is required.
Also, when a tuning of such accuracy as the perpendicularity is required, use only one of the
reamed holes.
• Shown below is the detail of the attachment area. Attach a load with the bolts listed in the table
below with the specified tightening torque. Pay special attention to the bolt length.

Regarding attachment screws
• Use of high-tension bolts meeting at least ISO-10.9 is recommended.
• Make sure to have the length of at least 1.8 times to the bolt diameter below for the effective
length of screw engagement for the tightening of a bolt and a female screw.
Caution: Pay attention when selecting screws. If a bolt out of the instruction is used, it may
cause damage on tapped holes or unexpected accident or failure due to insufficient
strength on the actuator attachment.
