The M66 Ring Mount wouldn't turn so we disassembled it and it's missing half the roller bearings and retainers. When it was demill torched looks like half the bearings fell out and got lost. Without the M66 data plate I can't find any mfg.
Does anyone have the dope on the roller bearings used or where to source(mfg) them.
It's unusual to look at all the M66 gov't publications

and find no info on this guy or even an exploded parts view. While on the other hand the M35A3 is completely described with exploded parts views from bumper to bumper every nut and bolt.
It uses crossed roller bearings similar to a Timken Tapered roller bearing, only on a big scale. So the bearings aren't tapered just .620x.620 dia. steel roller bearings.
Of course the 40 inch race diameter is the killer, looks like a large equipment bearing mfg.
I know someone will be selling a skidload of these on Ebay, after I'm done final assembly.
