    OK, I'm looking for something specific. My Senior Design team seems to think we have to buy a high-dollar actuator (fancy-pants engineering term) to do this but I don't think we do.


    Here is what I need:
    1. Dual-action pneumatic cylinder with a 6" stroke capable of moving 10lbs or less (probably around 4lbs, no side load)
    2. It has to operate at no less than 50"/second
    3. Ideally, it'd do a full cycle (up and down) in 230ms or less. One direction can be as slow as 170ms but the other direction needs to make up for it

    I have 250psi@5cfm right now but I can get whatever is necessary. Hydraulics is an option but since we're moving a small load we don't deem it necessary.


    Do you guys have any suggestions on where to look?

    Ebay......I've gotten many cylinders there. Most were new, for cheap. Ask the seller for the part number and look it up to see if it will work for ya.

    im sure you can get an electic actuator for the same properties. 4lbs is light for most actuators. with electrig you would save weight on the total of your project. or im assuming anyway, since it would most likely have a battery already.

    bimba http://www.bimba.com has a decent selection of cylinders that are pretty resonable. used a lot of them at work, just keep them away from heat.
