Hello all, I just won a few Bimba air cylinders on ebay and being new to the whole pneumatic thing I have a few questions once again..lol The one that I am looking to use right away has two holes one at the top of the cylinder and one at the bottom. Are the two holes what justifies it as being a "Double Acting" cylinder? and if so how should I hook the lines up for it to work properly? Thanks all your greatly appreciated. :jol:

Two holes does mean it's double acting. Gilderfluke has some diagrams that show how they plumb cylinders. They may be a bit more complex than really needed but it will give you an idea how it can be done.

This is a link bookmarked from my robot fighting days, it shows how to use a 5-port 4-way air valve to run that double acting air cylinder.

Just ignore the usage with high pressure

I am sure there are a few more good sites, just put in pneumatics for the HauntForum search and see what has already been discussed.
