2.3.2 Installation
[1] Installation of Main Unit
x There is a T-groove on the back of the base. When installing the body, utilize this T-groove
and hold the body with the T-nut enclosed with the actuator.
x The base has to have a structure with sufficient rigidity to prevent oscillation.
x The surface where the actuator will be mounted should be a machined surface or that with an
accuracy equivalent to it, and the flatness should be 0.05mm or below.
Ensure a room for maintenance work.
(1) Mounting Procedure
x The bolts for mounting the actuator should be of a dimension suitable for the mounting holes
and slot.
x Use hexagonal bolts for the actuator mounting holes.
x We recommend high strength bolts of ISO-10.9 or higher.
x Make sure to have the effective length of screw engagement described below or more for the
tightening of a bolt and a female screw.
x When female screw is on steel ĺ thread length same as nominal diameter
x When female screw is on aluminum ĺ thread length 2 times longer than nominal
diameter
x When attaching the base to a mounting table, use washers made for high strength bolt if the
bolts is M8 or larger or if the bearing surface is made of aluminum. A washer is not necessary
for M6 or smaller bolts. Do not use a common spring washer.
x The recommended screw torque is given below.
Screw Nominal Diameter Tightening Torque
M6 7N•m [0.7kgf•m]
M8 26N•m [2.6kgf•m]
x Use the T-nuts provided by IAI. (Please see drawing below).
x If you require more than the number included, additional nuts are available for purchase.
x When mounting the actuator, select a bolt length so that the tip of the bolt does not touch the
bottom of the T-slot.
x If you are purchasing brackets with the actuator, please use the bolts, nuts and washers that
come with brackets.
