McMaster has balls in stainless, 304, 316, and 440. 316 isn't the
hardest but is the most corrosion resistant. They are what I use for
rotator rebuilds.
If you meant "cratered" which happens when the mast oscillates then it
might be possible to smooth that out a bit with sandpaper since the
bearing is pretty crude to start with. Works for rotator races. Adding
a couple of grease fittings which get a shot of grease every year will
also help a lot. I like the TFE loaded full synthetic "Super Lube"
formerly by Synco, now owned by Loctite.

Ceramic balls have an issue, they really really don't like jarring loads. Their
failure mode is to break, vs rust

Does anybody know what size balls are in the Yaesu GS-065 thrust bearing? My cheap
caliper isn't precise enough. Looks like 3/8". They're rusted and bumpy.
Has anyone had experience with ceramic balls?
The grease is so hard I'm having to soak it off so I can see the races. If
they're crafted, I'll just replace the whole thing.
