Lead screws

I know AndyMark is selling those REV (?) linear actuators now, which are powered by leadscrews.

We have had good luck with "Fast-Travel Precision Acme Threaded Rods" from McMaster.

They can also be purchased from amazon with free shipping if you have prime.

I highly, HIGHLY recommend you go to Nook Industries to look at leadscrew options before you select a particular screw. They have a a LOT of free online information about lead screws and the selection process for them. You should particularly educate yourself about the different end conditions and the definition of critical speed. I had a sub-team that didn't believe me about the need to support both ends of the lead screws for our tote lift, and the screws nearly shook the system to pieces when they test ran it. After which they sheepishly admitted they needed to support both ends and started working on that.

The DART Actuators are made by IR3 Creative, not REV.
