[Load coefficient f ]
w
It is a coefficient to consider the life drop due to operational conditions.
Load coefficient f

1.0 to 1.5 Small vibration or impact in slow operation
[Attachment coefficient f ]
Attachment coefficient f is a coefficient to consider the life drop due to the condition of actuator
attachment.

* As the figures are those in common for each manual, they are not for RCP2/RCP2CR Slider Type.
Replace to figures for RCP2/RCP2CR Slider Type and select the attachment coefficient.
* Even when in attachment in whole area, and the actuator is seated in the whole length of the product,
select 1.2 or 1.5 for the attachment coefficient depending on the position of screw fixing.
* For attachment in whole area, use all of the tapped holes (counterbored holes) on the seat surface to fix.

Operation Life

The operation life depends on the moment to work. With light load, it will be longer than, the standard rated
life.
If taking 5,000km of the standard rated life as an example, with no consideration of vibration and attachment
condition, the operation life is 40,000km according to the calculation with formula in the previous page under
assumption that 0.5C (half of dynamic allowable moment) of moment is applied on.
M
It shows that it can be 8 times longer than the standard rated life, which is 5,000km.
