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.
