What is the thread size and pitch for the end of the pneumatic cylinders? I need to order some additional nuts as they tend to go missing.
The ends of the double action pistons are #6-40 (diameter #6 thread 40).
Not sure about the single action pistons, but they SHOULD be the same.
Single acting and double acting cylinders are the same.
Cylinders refer to the whole device, I’m specifically talking about the piston rod, sorry if I was a bit unclear.
You were perfectly clear: it’s just a pet peeve that the VEX community refers to pneumatic cylinders as “pistons.” (it’s no better in First, where they call the little DC motor a CIM, which is just the acronym of the Chinese factory that makes them). In my real job I design a lot of pneumatic and hydraulic equipment, and I’d probably be fired for incompetence if I ever started calling cylinders “pistons”!
