2.3.4 Installing the Load to the Slider
� There are tapped holes on the top surface of the slider. Affix the work part (transported object) here.
� There are two reamed holes on the top surface of the slider. Use these reamed holes if repeatability
of attaching and detaching is required. Also, if small tuning such as perpendicularity is required, use
one of the reamed holes for the tuning.
� Refer to the following table for the screwed depth and reamed depth. Screwing further than indicated
in the table may destroy the tapped hole or lower the reinforcement of the attachment of the work part,
result in the drop of the accuracy or an unexpected accident.

The tightening torque is follows.
• When the bolt-bearing surface is steel: 7.5N·m (0.77kgf·m)
• When the bolt-bearing surface is aluminum: 4.3N·m (0.44kgf·m)
Reamed hole
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 � Same length as the nominal diameter
Female thread is made of aluminum � 2 times of nominal diameter
Caution: Pay attention when selecting the screw length. Use of a screw with inappropriate
length may destroy a tapped hole or cause a lack in the attachment strength of the
transported object, which may result in a cause of an unexpected accident.
