Yoyo bearing that is mostly air/liquid tight

I was kinda looking into this, I abandoned looking. @AudreySickburn’s idea of the cleaning rubber sealed r188 bearings was my best bet.

Rubber bearing shields

Has anyone bought rubber shields to see if it would help a dry bearing stay clean, or even isolate the noise of a dry bearing? Been wondering this for a while, and I didn’t want to hijack the deepest state thread.
