If you got a piece of gear with grease zerks, wouldn't _you_ grease it
on the presumption they were there for a reason?

Anybody seen anything like this before?

Sure, happens not frequently but on occasion. Are the bearings really
sealed or just shielded in the latter case there is still a reason.

They're double shielded, the sealed for life throw away type. Only the
larger bearing for the variable speed drive (a sheave that slides up
and down a shaft) has a removable seal kit.

Was there a transition in the industrial motor world where they still
drilled and tapped grease ports in motor housings but just installed ball
bearings instead?

Or, just as likely, the original bearings were replaced with
sealed ones. And with the zerks in place, someone thoughtfully
greased the bearings.
Whether they needed it or not.
