^not formulas.
Well maybe they are formulas, but they'd be some kind of OEM formula hub that you can't buy anywhere. My guess would be Joytech/Novatec

Diacompe Gran Compe are another option


the suzue SIL-SP (Junior) hubs above are not that well sealed. And if you're using "Sealed" to mean "cartridge bearing" then they're not that either. Loose ball.
