4.2 Extended Cable track
The standard cable track that comes pre-assembled on large nut rotary actuators is used exclusively for
the wirings of the nut rotary actuator and has no space for accommodating any additional wirings the user
may require.
Accordingly, extended cable tracks are provided as options to accommodate user wirings.
The standard cable tracks that come with small and medium types have a space to accommodate user
cables. Refer to the following page.

Standard cable track specification
Extended cable track specification (optional)
The points to note when storing cables/hoses in an extended cable track (optional) are specified
below:
[1] Provide a minimum clearance of 2 mm between the outer diameter of the cable/hose bundle and
the interior wall of the cable track, and also between the individual cables and hoses.
[2] Use cables/hoses with an outer diameter of I16.8 or less, and arrange the cables/hoses
horizontally by making sure they don’t cross with one another.
Take note that if the cables/hoses are stored without observing the above precautions, the
cables/hoses will receive an excessive force and their life will become significantly shorter.
