Max. Stroke - SMC Networks CS2 Operation Manual

2) Max. stroke

Bore size
！
Caution
Cylinder should be operated within the max. usable stroke.
Operation at the stroke beyond the max. stroke could cause breakage
of piston rod.
Also since there are some cases where piston rod could break at the stroke
less than the max. stroke depending on the application, please refer to "4)
The relationship between cylinder size and max. stroke by the mounting
style" for the max. usable stroke.
3) Max. usable stroke by the lateral load given to the cylinder
The area within the solid line shows the relationship between the specified
length stroke cylinder and allowable lateral load. The dotted line in the graph
shows the case beyond the long stroke limit.
i) Judging external lateral load.
It is recommended to use fixed type cylinder so as the lateral load would
not apply to the piston rod, however, in case it is not avoidable, it needs to
be checked, if the lateral load is within the range of safety.
How to judge: The area within the curb line of graph 1 shows the
