Linear&Rotating Pneumatic Device?

[RMG143]

Looking for a double acting pneumatic device which both translates and rotates at the same time. The application is for being the device to be bolted to a machine then screwing and unscrewing a screw. The device would likely utilize a threaded rod of some sort and would be attached to the screw through some machined adapter.

Technical specs. are not available off hand and I figure any company making something like this would have a range of options. Any help would be appreciated.

Thanks

You need to give a little more information.

Based on your OP I would look at a spring loaded nut runner with sliding sockets and/or spindles.

Festo makes these:

We have not used this particular type but on a previous project we had a pneumatic linear actuator with an integrated electric motor controling the rotation.
