Ex.) 25A-CS2F125-300
According to the graph 1, nodal point of cylinder stroke 300mm and
Φ125 is 115N. Lateral load to rod end needs to be smaller than this.

ⅱ Judging lateral load of dead weight
In case of rotating type cylinder, lateral road applies to the piston rod
because of dead weight of the cylinder. It needs to be checked, if the
lateral load is within the range of safety.
How to judge
Use graph 2 or 3, either of the one applicable to the mounting bracket and
bore size of the cylinder, which are used. Check if the stroke of the cylinder
model is smaller than the allowable stroke.
Ex.) 25A-CS2D125-450, mounting angle 0°
This is clevis type, so use graph 2 and read nodal point of mounting
angle 0°and curb line, which is stroke approx. 480mm. The cylinder
stroke 450mm is smaller than this stroke, therefore it is safe.
