Air leakage from
the
shaft.
Piston packing is worn
out.
Please confirm the presence of the
wound in the cylinder inner wall after
cleaning the inside of the cylinder. Please
do the following treatment on that.
(1)Please exchange packing when
there is no wound in the cylinder.
(2)Please exchange it for a new
actuator when there is a wound in the
cylinder.
(3)Please when very dirty in the
cylinder inspect the air filter, do blow
air through the piping

The pinion gear is
broken.
Excessive kinetic energy
was applied to the rotary
actuator.
Replace with a new actuator.
Please do the following treatment on
that.
(1) Calculate the kinetic energy applied
to the rotary actuator, and adjust the
load and rotating speed so that the
kinetic energy will be within the
allowable range.
(2)
Please install the stopper or the
shock absorber outside and absorb
the impact power.
In this case, please
provide a buffer angle to the stroke of
the actuator
（
Use 100° actuator in
the case of 90° stroke and use 190°
actuator in the case of 180° stroke.
）
and touch it to an external stopper or
the shock absorber surely.

(With the air cushion)
It doesn't become the
best the adjustment of
the cushion valve,
and the kinetic energy is
unabsorbed in the
cushion.
Replace with a new actuator.
Please do the following treatment on
that.
(1) Please adjust the cushion valve
best.
(2) Please the kinetic energy where the
load is generated is cushion
absorption energy or less or check.
