| Theyre just linear actuators. I've never had that part of them apart, but they're pretty simple. A motor that turns a screw. Reverse ploarity to make it go in the opposite direction. If yours is junk, I'd tear it apart to see where it's breaking and decide how to proceed.
There's 3 places off the top of my head that sells them different sizes and power ratings.
Surplus Center sells them, as well as:
Progressive Automation: progressiveautomations.com
And: Servo City: servocity.com
Most come with internal settable stops so you can find one with a close stroke to what you need and adjust it once you get it ready to install. | |
