I managed to come up with what I thought would be a good air cylinder to mount on my 4x6 import horizontal saw to replace the spring. It is a NorgenN76025/125. Which I cannot find any documentation on. I think this is all metric, as the 125 is the approximate stroke length in mm and the bore is probably the 25. The problem lies in the ports. They are about the same as 1/8 NPT, but the thread pitch is much finer and they are not tapered. Any ideas what I am looking at here?
