RE: How about this for a thrust pad material?

Maybe the range of properties of common T.C. industrial doodads falls in a pretty narrow band. I.e. the recipe for the material varies but not by much I suspect. There are all sorts of ASTM and Mil-Spec standards but they are hard to sift through. If you want to get deeply technical stay awake through this: http://www.generalcarbide.com/assets/pdf/GCDesignerGuide.pdf

In any case your bearing will only be using like 1% of the ultimate performance capability of the T.C. pad, so I wouldn't sweat it.

Look at the other handful of manufacturers of these sorts of pads and miniature bearings in the US. Google: solid carbide pad . Newport makes a good looking little bearing: https://www.newport.com/medias/sys_master/images/images/hf6/ha2/8933928927262/CPP-F-6-317.pdf

Tre's idea for the sapphire watch crystal is the brilliant one though- small generic ones are for sale on eBay under "watch parts" for around $10 bux- if you trust it's a *real* sapphire crystal.

I suppose the bearing could be anchored safely for these sorts of loads with some fine high strength adhesive. General Carbide recommends this LocTite 324 stuff- never used it but it looks bitchin! They say you also need the matching activator. Read up- it's expensive. Don't glue your hand to any turntable parts- I've tried that before that and it sucks!
