Large iron?

Found in louisiana at a skirmish site. Not sure what it is

I can tell you what it looks like as a guess. It looks like a brake pad to stop a shaft from turning. I have an identical part on my Edson wheel steering on our sailboat but 1/5 that size. Liner bearing and all. Perhaps that is for a larger shaft?

Might also be a bearing. Looks like Babbet metal lining.

certainly looks like a bearing
I think I see an insert keyed in the inside curve.
maybe lead or brass insert?
