",
refer to the contents below for configuration and selection.
[Standard load coefficient: f

]
For ELECYLINDER described in this manual, calculate with f
ws
= 1.2.
[Load coefficient: f
w
]
This coefficient allows consideration of the effects on life due to operating conditions.

This coefficient allows consideration of the effects on life due to ELECYLINDER mounting
status.

● The actuator used in the explanatory figures above is not the ELECYLINDER.
Replace with ELECYLINDER and select the mounting coefficient.
● Even when seated over the total length of the product, select 1.2 or 1.5 for the
mounting coefficient depending on the position of screw fixing and not "fixing over
the entire surface".
● Various mounting methods are available for the ELECYLINDER.
"Fixing over the entire surface" is considered to be the case only when fixing with the
T-shaped slot and square nut provided on the mounting surface.
