If removing pipes is difficult because the piping space is very
constricted, consult your nearest Koganei sales office for a
specialized tool that is available.
Specialized tools for removing tubes
Handling instructions and precautions
●
Usable tubes
Use of both nylon tubing and urethane tubing are supported.
Nylon tubing outside diameter precision should be within
±
0.1
mm [
±
0.004 in] (nominal) for nylon tubing and within
±
0.15 mm
[
±
0.006 in] (nominal) for urethane tubing. Use tubing with ovality
(difference between major axis and minor axis) within 0.2 mm
[0.008 in] (use of Koganei tubing is recommended). Use of tubing
that is not a Koganei genuine product or a compatible
(recommended) product may result in tube disconnection, air
leakage, or other problems. Be sure to check on tubing before
building a pneumatic system. Also, note that you cannot use the
conductive urethane tube U2A-B produced by Koganei.

NOTE
1. Use tubing with an exterior that is not damaged. If tubing
becomes damaged after repeated use, cut off the
damaged portion.
2. Do not allow tubing to become severely bent or twisted
near the connection to a fitting. Such a condition creates
the risk of air leakage. The table below shows minimum
radius guidelines for nylon and urethane tubing.
3. Do not use extremely soft tubing, which causes a severe
drop in pull-out strength.
4. Before removing any tubes, always turn off the air supply.
Also, be sure to confirm that the air inside the pipes is
completely vented before starting.

Speed adjustment for actuators
①
To increase the speed
Start with the needle of the speed
controller fully closed and turn it
counterclockwise to increase the
speed of the actuator. When you
reach the desired speed, be sure
to tighten the lock nut so that the
speed setting does not deviate.
②
To decrease the speed
If you turn the needle of the speed
controller too far (the speed is too
fast), turn it clockwise to decrease
the speed. When you reach the
desired speed, be sure to tighten
the lock nut so that the speed
setting does not deviate.
