The 100T-E, 150 ton, and 200 ton cylinders are all double acting. You can see them HERE. It’s worth mentioning that though these cylinders are in-fact double acting, they are not used in such a manner when installed in our presses because the connection of the cylinder to the press frame will not support the strength needed for pulling. Thus, our presses are only for pressing, not pulling. This naturally means we have not tested our cylinders under load in a pulling scenario. While that may seem odd, please understand it’s similar to asking a man how fast his truck can go in reverse; he probably doesn’t know. Thanks for shopping with us!
