Hey Bob, I've got this damned Hardinge threading attachment that called it out for lubricating the internal parts. I got some Molykote 1122. It's EXPENSIVE AS HELL, but at these speeds, I think it might be ok.
Hard to know without a specification that you can find the properties of. There are lots of moly greases out there, try to get one of the proper viscosity for what it is doing, and how fast it is doing it.
The spec'd product is an aerospace rated silicone base Moly grease. Which solar system are you sending your threading attachment to? It is a Hardinge, not a Lockheed Martin. Use an appropriate grease for the speeds, materials, and loads if it won't be running 24/7/365 under crazy conditions.
There's a dry lube spray, M88 by name, that might be the item you want. The 'Molykote' brand is now a Dow/DuPont
tradename, so is likely to offer a lot of dissimilar items under similar names, mainly silicones. The dry spray was likely based
on molybdenum disulphide.
I have used dry MoS2 (molybdenum disulphide) powder (sort of like the graphite you ”squirt” into hinges and locks to free them up, and Locktite brand molybdenum grease for a lot of stuff over the years, and swear by the stuff. My old 1960’s furnace has a huge (but very quiet) blower that has bearings that have been going out for the last 30 years that I’ve lived here. The bearings are almost impossible to get to for service unless I tear out a couple of walls for access. When they started squealing I devised an oiler that I can snake in between the fins and get to the grease cups. This worked for a couple of years but required oiling about once every other month. Then I tried using the locktite moly grease, which is more af an oil than a grease. Really messy stuff, but I haven’t heard a squeak for the last 4 years. It just spins quietly. Fantastic stuff. I suspect some day down the line I’ll have to tear out the walls and replace the bearings, but till then....
Moly is an amazingly slippery material and when suspended in oils or greases becomes a true super lube.
It’s messy to use, but man does it work for every thing I’ve ever used it for.
