Note 1) Strokes other than the above are produced as a special order.
Note 2) The maximum value of the horizontal workload (an external guide
is necessary).The actual workload will depend on the type of
external guide.
Note 3) Thrust setting range when "pushing" operation in torque control
mode, etc. Set it referring to the thrust conversion graph shown in
the catalogue as a guide.

Note 4) Allowable impact speed when "pushing" operation in torque control
mode, etc.
Note 5) Impact resistance:
No malfunction occurred when the actuator was tested with a drop
tester in both an axial direction and perpendicular direction to the
lead screw (The test was performed with the actuator in the initial
state).
Vibration resistance:
No malfunction occurred in a test ranging between 45 to 2000 Hz,
when the actuator was tested in both an axial direction and a
perpendicular direction to the lead screw (The test was performed
with the actuator in the initial state).
Note 6) Only when the motor option, "with lock", is selected.
Note 7) For an actuator with lock, add the power consumption for the lock.
Note 8) A reference value for correcting an error in reciprocal operation.

4 Installation
4.1 Design and selection
Warning
Do not apply a load in excess of the actuator specification.
A product should be selected based on the maximum work load and
allowable moment.
If the product is used outside of the operating specification, the eccentric
load applied to the guide will become excessive and have adverse effects
such as creating play in the guide, reduced accuracy and reduced
product life.
Do not exceed the speed limit of the actuator specification.
Select a suitable actuator by the relationship of allowable work load
and speed.
Noise or reduction of accuracy may occur if the actuator is operated in
excess of its specification and could lead to reduced accuracy and
reduced product file.
Do not use the product in applications where excessive external
force or impact force is applied to it.
This can lead to premature failure of the product.
4.2 Handling
Caution
Do not operate by fixing the piston rod and moving the actuator
body.
An excessive load will be applied to the piston rod, leading to damage to
the actuator and reduced lifetime.
Do not operate by fixing the piston rod and moving the actuator
body.
An excessive load will be applied to the piston rod, leading to damage to
the actuator and reduced lifetime.
4.3 Mounting
Caution
When mounting the product, use screws with adequate length and
tighten them to the recommended torque.
Tightening to a torque over the specified range can cause operation
failure, and insufficient torque can cause displacing or dropping of the
attachment.
