Isn't a pneumatic cylinder on its own already a piston-in-tube device?

You could shave some weight off if you used a bracket to secure a tube to the nose of the cylinder so that only the piston rod is enclosed. You might need to rethink mounting, but the weight saved would be non-negligible. In addition, it could be argued that such a design would be more faithful to the name.
