A fixed throttle is installed inside the actuator port. Do not increase the size of this hole by re-machining,
etc. If you do, the swing velocity of the actuator will increase, causing the shock force to increase, which
may damage the actuator.
When pressure is applied from the B side port, the shaft swings in the clockwise direction.
The body of the rotary actuator is equipped with a
direction indicator plate to indicate this.
Perform followings before piping.
a) Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove
chips, cutting oil and other debris from inside the pipe.
b) When screwing piping or fittings into ports, ensure that chips from the pipe threads or sealing material
do not enter the piping. Also, if pipe tape is used, as in Fig. (11), leave 1.5 to 2 thread ridges exposed
at the end of the threads.
Operating air
Air supplied to the rotary actuator shall be cleaned by
the filter. CRA1 series is lubrication free.
