4 .2 Mounting Considerations
4 .2 .1 Alignment and Side Loading:
Alignment of the actuator with respect to the application load and axis of motion is essential to
minimize side loading. The IMA-S is not meant to be used in applications where side loading occurs
as side loading will reduce the life of the actuator and rod seals.
4 .2 .2 Side Load Considerations
The IMA-S integrated motor actuator is not meant to be used in applications where side
loading occurs. Loads must be guided and supported. Loads should be aligned with the
line of motion of the thrust rod. Side loading will affect the life of the actuator.

4 .3 Mechanical Installation Instructions
1 .
Remove packaging
2 .
Carefully remove linear actuator from package. *Consider the weight of the actuator.
Depending on the configuration, the actuator can weight up to approximately 22.7 kg (50 lb)
3 .
Visually inspect the actuator for damage
4 .
Notify the carrier of any shipping damage immediately
5 .
If the actuator is mounted in a vertical or inclined (sloping) position, include safety measures
that control the work load in case of a screw failure.
6 .
Consider anti-rotation of the rod end. The actuator’s thrust rod must be kept from rotating
in order to achieve linear motion. If the application’s tooling and load is free to rotate, order
the IMA-SA model with internal anti-rotation to prevent the rod from rotating.
7 .
It is recommended to install the actuator with rod-end down or at a downward inclination to
achieve best seal ingress protection.
