Re: Pneumatic Rotary Actuators Questions
The rotary actuators work by taking the linear motion of a pneumatic cylinder rod and converting it to a rotary motion.
Basically, you connect an air line to each end of the actuator. By pressurizing one end, you will turn the center shaft, usually about 90 degrees. By pressurizing the other end, you will rotate it back past center and 90 degrees the other direction. The Bmba site says they make them from 45 degrees to 1080 degrees (3 turns).
With 60 PSI to work with, you get limited torque output, but there are some specific places where these are beneficial.
If you these, be very careful with the end connectors for the tubing. The threaded connection to the cylinder is very small and a slight impact can break it off.
