Linear actuator or pneumatic cylinder? Need guidance

[rudyeb]

I am designing a machine that will need a pin (.094"dia) to move back & forth approximately .750" max. I need to be able to control the position of the pin to about +/- .005/.010". Can pneumatic cylinders or linear actuators be controlled to do this?
Perhaps there is something better? The pin would move forward in response to a limit switch but needs to return 1/4 of the way back and then after another impulse it will fully retract. What would be the best setup including a cylinder/actuator and some means of control?

Thank you

Hi rudyeb,

This look really precise, we would suggest a linear system either belt driven with a stepper motor or screw driven.
A linear actuator might not give you that precision level.
