Given the visible wear I'd say this failure was due to something else, not the rocker. That could have been a Harland Sharp rocker and the same thing would have happened to it.
I disagree, it looks like that rocker hole is on a slight angle or the needle bearing was installed cock slightly so the bearing end rub against the bottom part of the bearing end, something hard enough to wear into, eat into it, causing that failure
