In the case of the force control line-up, the actuator having rated load more than 27N and self-lock feature can be used for the Z-axis application. The actuator having rated load less than 27N cannot be used for Z axis application.
Rated load only
The use in the Z-axis (vertical) transfers more load to the actuator during acceleration/deceleration due to gravitational acceleration, which may affect durability. Apply the Z-axis load only below the rated load. If you control the load more than rated load, the lifespan may deteriorate rapidly.
