A Chinese company now manufactures stainless steel tip cases for ballpoint pens

There is also the material science of the rolling ball itself. I assume it has similar constraints to high quality bearings.

Good point. But if they can't manufacture ballpoint pens, how can they make bearings? Maybe it's due to their small size?

This article is talking about the tip casing, not the actual ball.

I took that to mean the ball and the housing around it. The casing would function similarly to a bearing race and the ball to well, a bearing ball.

Ballpoint pens might be a hard problem. The article didn't say they couldn't make them, it said they couldn't make them as well as others.
