Re: How does the rotary actuator work?

It is designed to let you use compressed air to make a rotary movement -
maybe twist an arm or bracket or something else. It can replace an electric motor and potentiometer / limit switch set up., but you are limited on the cabability (basically 0 or 90 degrees and nothing in between).

Re: How does the rotary actuator work?

Just from looking at it, I can guess (not certain) that there is a simple rack & pinion inside. The rack is pnuematically driven inside the cylinder, and the pinion is attached to the output thus making linear into rotary motion.

For this year, we are limited to 90 deg of rotation, but at our pnuematic workshop we were told there are limiting screws taht can be adjusted to let it turn up to 320 deg under internal limits only.

Re: How does the rotary actuator work?

I think the main thing that anyone needs to keep in mind when they use them is that these are not motors. they canot complete a revolution, however thay can go from say tharting position, and turn 90 degrees. they might me usable at the end of an arm to close a grabber, since they are light.

Not true. Their are capability between 0 and 90 and extend and retracted. I'm working on a white paper to show how. We used the capabilities on our pneumatic lift last year.

Re: How does the rotary actuator work?

I had a question about the rotary actuator... are we allowed to order a rotary actuator that moves beyond 90 degrees? I was hoping for one that could move 180 degrees. Or is there some legal way of adjusting the rotary actuator to move beyond just the 90 degree limit... if so, how? Thanks very much!
