As a general rule, if you are designing a system that demands forces other than along the the push/pull line of action, other components of the system need to handle those besides the pneumatic pistons themselves.
A go-to mechanism I always prefer is cascading drawer sliders, you can get these in oodles of lengths and loading capacities, with compact, reliable, and robust construction, and they sell them at Home Depot and Lowe's, or lots of places online |
Good thing you guys got to us before we built this thing, I was quite afraid of this.
