Look at the surfaces and see if poorly machined/have "chatter". Lay a straight edge across on quadrants. Shine a light behind. Shouldn't be any coming through.
You can take a suitable inside caliper and measure for roundness.
I'd take them back, if I wasn't satisfied.
Like they say, this used to be common, but not so now. Many parts places don't even have a drum machine any more.
If they know how to run the machine they would know if the bearing needed removed or not.
I don't really recall, I haven't had a drum turned for ~4 decades now, rotors not even much. New ones are as cheap but not for "P"s. I'm pretty sure watching my friend at NAPA, too long ago, the race stays to fit/center the drive end. But I wouldn't bet anything on my memory.
