Have checked Ebay for bearings ? I find a lot of obsolete stuff there, Mike.
The very last place one should buy bearings from is ebay or amazon
while there are some genuine NOS bearings sold there, most are fakes or quality control rejects .
The most faked item on the planet is bearings , not expensive watches .
Lots of factories make $ 1.50 bearings then etch a quality company name on the sides and ell them for $ 10 by the thousands to clots who think they are getting a $20 bearing for $ 10 then go on social media to tell every one that brand XYZ bearing are now junk .
Bearings should always come from a bearing shop, over the counter so you know that it is a real shop with real bearings.
Next best is a real parts store, one with a nice big glass window you can throw a rock through if they sell you fake bearings
One down from that are genuine internet specialist that have a name you have heard
I Sell cheap cheap , Number 1 bearing shop , Good cheap etc etc etc vendors on Scamazon & Evilpay will sell you junk .
