Allowable Static Load Moment
[N•m (Kgf•m)]
Allowable Overhang Load Length (L)
20 (2.04) Ma direction: 200, Mb or Mc direction (Note 1)
Mb/Mc directions
Ma direction
Note 1 Avoid applying moment load to Mb or Mc direction during an operation.
1.2.7 Duty Ratio of Continuous Operation
During continuous operation, the actuator generates frictional heat due to sliding of the pipe over the
wear ring.
Since higher pipe temperatures reduce the clearance between the pipe and wear ring, shorten the
actuator life or cause other unwanted conditions, use the actuator at a duty of 50% or below.
Duty (%) = Operating time / (Operating time + Stopped time) × 100
1.2.8 Drop-proof Performance
Although the protection class is equivalent to IP67, there are some restrictions as shown below:
Ɣ Consult IAI beforehand, if the actuator will be used in an environment subject to splashes of liquids
other than water.
Ɣ The actuator cannot be used in an environment subject to splashes of viscous liquids.
Ɣ The actuator cannot be used in water.
Ɣ Structurally the actuator is designed to withstand washing with water, etc. However, the actuator
cannot be immersed in water, as it will cause the slide bushes to swell or create other unwanted
conditions.
1.2.9 Dust-proof Performance
The electrical parts of the actuator, such as its motor and encoder, are designed to completely shut off
dust. As for the moving parts (such as the sliding parts of the pipe and slider), the gaps are covered with
felt seals. Despite the above measures, however, dust may still enter the pipe and slider or underneath
the seals. Since such dust may damage the actuator or cause other unwanted conditions depending on
the type and state of dust, the actuator should not be used in the following environments:
Ɣ Environment where magnetic dust particles are dispersed or suspended
Ɣ Environment where polishing agent or other abrasive dust particles are dispersed or suspended
