If the cylinders are single action each needs to take the full load. If
double acting it gets more complicated both in calculation and
installing. The pulling force is reduced by the area of the rod.


Excuse my ignorance, but how can I tell if the cylinder is double action or
single. I've just looked at the Vetus catalogue and cant see any reference
to single or double?


For
example a 2" cylinder with a 1" rod will have a pull force about 75% of
the push so you can't quite divide by 2.

I kinda thought that it would just be as simple as divide by 2...



thanks again
