I fully realize there are likely many sizes...
But I've been beginning to wonder lately, if many arms didn't use one size ball bearing in the horizontal bearing assembly...
From disassembling several, it's starting to look that way.
I haven't measured any of them... don't have measuring tools that precise...
Beginning to wonder also, if there wasn't one company (or a small handful) that made all
the arms for the big name brands....
In case that goes nowhere...... the arm in question, that I'd like to replace the balls of...
The free (non caged) horizontal balls.... in a Synetec S-220 (aka: Piezo PU-402 aka: Sedco-Sparta S-220 and possibly Jelco TS-503)
Also starting to wonder... if the company behind Jelco just made most of the mainstream Japenese arms of that era....
Anyway... my main interest... is to determine what size ball bearings are correct, and preferably where to get some...
TIA!
