Re: Hydraulic Ram
The machine you referenced is called a 'Jackscrew mechanism'. You can use all-thread and nuts, or the nicer version uses Acme rod with Acme nuts.
Also a forum sponsor Actuonix makes several plug and play linear actuators, that can be run as either a linear servo that self centers or an actuator that holds position. It would be cheaper than hydro. They even have built in micro switches at travel limit.
