I cant answer your question on res, however I recently worked on a project which involved making machinery smart, and counting shaft turns for warranty and parts delivery. The sensor box was a standalone unit and 'sealed for life' with 4 AA batteries which could keep it running for 8yrs. The device pinged daily with an update on rpm/shaft turn count. Getting a sensor which was low energy and easily integrate could have been this bearing but looking at current requirements it wont ever be this bearing now.
Does any bearing exist with a reed switch type trigger per rev sensor?
