Just reporting back for an update. The problem with my spinner was 100% related to the bearing that came with it.
$8 box of Bones Reds from Amazon fixed it right up and now it's perfect. Super smooth and quiet, as it should have been out of the box.

NeWaVdubsOne thing of note as well, the Bones Reds I have came lubed with their speed cream or whatever they call it, so that does decrease spin time, but makes the spin very smooth and quiet. If you wanted longer spin time, I suppose you could take the shields off the bearings and clean the lubricant out with a citrus solvent or simple green or something, but personally I care more about smooth and quiet spins than spin time as I just use my spinners to fidget back and forth with most of the time and don't really table spin them.
rsnblmnEvery spinner I've popped either of these bearings in, I pulled the dust shields, and dipped them in my ultrasonic cleaner, and blew them off dry. I ran them dry and never had issues. After a couple days they quiet down a bit, and spin longer and smoother. I have since sold or given away all my 608 spinners, R188s rule the roost. I may have to machine my own R188 adapter for a press fit to both bearing and spinner, but I have to wait until my 2 RAMA spinners arrive to see what the deal is with the ones I'll get.
NeWaVdubsYou are much more hardcore than me. :)
I agree, I prefer R188s as well. I'm sort of surprised they weren't used here as they do seem to generally be better quality or better suited for this application...or both.
rsnblmnUltrasonic cleaners are pretty cheap, got mine at Harbor Freight for $65. Holds 2L of water, add a sprinkling of soap, it'll clean almost anything. It's awesome. If you work on cars or anything that has small parts and gets really dirty, it's totally worth it. They make tiny ones for jewelry you can probably find for under $40.
NeWaVdubsI've been through several brands of ultrasonic cleaners and have bought them for family members. What I can say about them is that (1) they are great while they work, and (2) they don't last very long. I've had them last just long enough to pass the warranty date, and I've had them break soon enough that I was able to get two replacements within warranty.
So you need to consider ultrasonic cleaners as something you will need to regularly replace.
I can't make a judgment about these stainless steel, lab-grade, built-like-a-tank ultrasonic cleaners you see at places like eyeglass retailers. Maybe they last longer. But what breaks on consumer models is something electrical, not the external casing.
CloacaMy Harbor Freight model I bought in 2007-08. I use it at least once (for a good portion of a day) every couple weeks. I must have lucked out. The old machine shop I worked for had an all stainless 1.5L Chicago Electric (also HF) and I'm pretty sure he's been using that one daily for almost 20 years. Maybe they used to carry decent stuff back then. LOL!
