The actuator mounting surface should be machined or otherwise processed to a smooth surface
of equivalent precision.
• The effective depth varies depending on the actuator model and mounting surface. Determine an
appropriate length for the screws to be used by referring to the figure below.
• Circular and long positioning pin holes are provided in each mounting surface. Use these holes if
necessary.
Ɣ GS3NA, GS3N (Lead screw, ball screw)
The actuator is structured in such a way that it can be affixed on any of its four sides. The load
can be installed only one side.

Caution : Some tapped mounting holes are through holes. Never use long screws exceeding
the effective thread length. Such long screws may damage the internal mechanism
or electrical parts.
