Installation overview
The non-guide type actuator cannot be operated without an anti-spin mechanism for the ball
screw shaft because the shaft rotates idly. Be sure to provide an anti-spin mechanism such as
a guide rail or a movable plate.

With the non-guide type actuator, the customer is required to perform centering between the
actuator and anti-spin mechanism. The installation method varies depending on whether the
component parts of anti-spin mechanism have an accuracy that centering can be performed.
If the component parts does not have enough accuracy to perform centering, jigs (centering
shaft, centering adjustment plate) are needed.

* It is used when the accuracy of component parts is not enough to perform centering. Also, it
is used when the stacking tolerance of parts is adjusted.

Be sure to check the installation accuracy using a feeler gauge and others. Low
installation accuracy may result in malfunction or shorter service life of the
actuator.
•
When the electromagnetic brake type actuator is used, refer to p.26 to release
the electromagnetic brake before installation. The ball screw shaft cannot be
moved unless the electromagnetic brake is released.
