Wait.... You didn't bevel the edges? Smooth the casting lines or weld fill any unnecessary holes?!? You just changed bearings and installed them???Some much needed maintenance on the metal cutting bandsaw.

Once I had it out and the side rollers out, I realized that it was actually cracked in two places. I’m lucky the whole thing didn’t come apart on me in the middle of a cut.

Done, and much better now. I’ll keep the non-cracked one as a spare in case this ever happens again.
