● The above strokes indicate the maximum available strokes for<br />
the standard type. For the rod buckling, check with the buckling<br />
chart of the selection materials. If you request the strokes<br />
other than in the table above, contact us.<br />
● Please refer to the 140L-1 series beyond above mentioned<br />
strokes. (140L-1, bore:63mm to 160mm, Maximum:3000mm<br />
stroke)<br />
*140L-1 series is specilly designed for long stroke, so not interchangeable<br />
with H-8 series.<br />
