DIY Bearing availability

there are a couple of bearings being sold on ebay. Also aluminum and POM platters to match. they are being made in China, but what isnt these days.

You might also check an industrial components supply outlet like Graingers. I think they carry an assortment of bearings:

If you want a fully developed dedicated turntable bearing complete with housing and mounting capability, try a search on Lenco Heaven. There are two guys, Mirko and Jeremy, that make very nice bearings suitable for use with platters other than the Lenco one. Moreover, I am sure either or both would custom make you a bearing suitable for much heavier platters, if that is your desire. I am the satisfied user of a Jeremy Superbearing in my Lenco.

Here's one:

Thanks guys. The Grainger and DIY Hifi bearings are totally unsuitable for what I have in mind. The bearing on LH is closer, I'll have to look into it. The Chinese stuff is quite comical.
