In the trade, it's a linear actuator. The company I worked for made motorized slides, but much larger, able to hold 500 Lb. about three inches off the face of the slide block. What we made were similar, using limit switches. However, we also made some that had a slip clutch between the worm gearbox and the Acme screw. If it bottomed out, the clutch would slip. We used them to position welding heads on automated welding equipment. That type of limit switch assembly can be found on certain electric hoists. Yale, in particular.

Nice, what will you do with it?

We need a store like that on the East coast (near Boston please). I never got to see "radio row" in Manhattan.

[@jj74qformerlyjailbreak3]

I request one in Southern Ohio.

[@nickcaruso]

there used to be a couple. Hefron's in Cambridge and one whose name I forget off 95/128 near Cummings Park. That one retreated to Manchester NH but I think that's gone now.

[@WECB640]

@@nickcaruso Yes. I've been to the Manchester NH store. Eli Hefron's was well known by the students at MIT. I recall Olson Electronics too. Thanks for the memories.

@@WECB640 I have a friend who grew up in NYC and did get to see Cortlandt street before it got "redeveloped".

Radio Row in was the greatest place to visit for me. I am 75 years old and lived in Manhattan. When I was in my teens I would either take the subway or walk. The amount of military surplus was amazing. There were stores that specialized in components, vacuum tubes, test equipment, etc. It was displaced with the construction of the World Trade Center. I often wondered how long Radio Row would have lasted. Rents would have eventually driven all the stores out of business I guess. Although there are not many stores left, there are stores that specialize in plastic (sheet), and machine parts (motors, etc.)

[@brauhaus]

what store?

Dig out the motor. maybe they're Maxon? I bet these were one-offs.

[@urlkrueger]

Not a stepper and no feedback other than limits. Hmm? In a printer recently took apart there was a plastic strip with encoding marks on it and an optical sensor. Add an Arduino and "Bob's Your Uncle!".

[@stamasd8500]

They're probably meant originally for the manual control of something. Likely supposed to be used with the good old "eye" feedback. :)
