Caution
1. Each switch and mounting style of
cylinder has a different minimum
mountable stroke. Be especially careful
of the center trunnion style.

Note 1) Intermediate strokes other than the above are produced upon receipt of order.
Spacers are not used for intermediate strokes.
Note 2) Long stroke applies to the axial foot and the rod flange.
When exceeding the stroke range for each bracket, determine the maximum stroke
referring to the Selection Table (front matter 29 in Best Pneumatics No. 2).
