McMaster-Carr, looks like about $19 plus shipping. https://www.mcmaster.com/gas-struts Shipping gets calculated after order, but it would surprise me if it's over $10 from them. Now...the length AND return pressure, i can't help with. I'm guessing relatively low, like 20 pounds...maybe 30. Good luck!!

I constantly have requisitions in my manufacturing plant, for specialty items, similar to this item. We have a great local source, but if the item cannot be had there, or has a long lead time, I have these back-up sources:

MSC
McMaster-Carr
Grainger

Is there a part number on the strut itself ?, not just a part number in the manual.   If so  that will probably tell you all the specs and be able to get a replacement.  Roly

I looked and found nothing as far as markings go.

Steel City is no more and I'm wondering if these are standard units. If so, are all similar units the same? If I bought a Powermatic or Grizzly would it work. The body (tube) is around 6" long but I'm not sure how they rate the strength. 

Has anyone had a similar situation and what was your solution? Can I stop at an auto supply and pick one up and have it work?

Thanks

Mark, "Little Machine Shop " web site has an air spring made for mini-mills that might work. $14.95 plus shipping. Part # 4079 under Replacement parts. Also you might do a search for pull down ladders with air springs. I recall installing a couple of them but do not recall the info on the air springs themselves. I had an air  spring on a mini-mill. I did not like it ,and changed to a pulley and weight system that I liked much better.
I controlled the counter weight with a gallon jug of water. I added water to the jug til the head was balanced. When I sold the mill I gave the air spring to the buyer.

My Steel City Mortiser has done the same. Have you found a solution? Will be watching.

$35 plus shipping is probably about right. If it's the correct part it's worth it. The machine is terrible to use without it. At least mine was.

The gas strut on my Steel City mortiser has also failed.  Where did you find one and what were it's specifications.

Thanks.

All auto parts houses has a rack with a decent selection.
Take your old one in and compare.
