    I have a application that required a piston to be constantly in rotation.
    The process goes like this:
    Piston extended. End of piston rod will be pressing on workpiece, while workpiece is rotating.
    Which in turn will rotate the piston rod constantly as well.
    Is the pneumatic piston able to take the constant rotation, will it wear off?
    The speed is about 5 – 6 rpm.


    I think you will need to consult an engineer from a cylinder company. A rotation of the rod from time to time can normally be handled fine but 5-6 rpm consistantly will require additional engineering for the piston and rod bearing. What about using a rotating coupling instead of rotating the entire cylinder?
