Something to consider as well....

In our design we were considering using a number of large stroke pneumatics to pull up stages in a lift, and realized that we could reduce those stroke lengths significantly by using pulley systems, effectively using mechanical advantage.

The picture attached basically shows that by pulling the lower pulley down, it will require twice as much force, but make the other end of the string around the upper left pulley move twice as far (and twice as fast). Most pneumatics have much more force available then what you'll need, so this might be an effective way to reduce the required stroke lengths, if this is indeed your application.

If it's not, then maybe someone else will enjoy another addition to the collection of world famous art, aptly titled, "Art by Matt"
