Should of bought plastic bearings. But they are expensive.
Exactly what I am thinking, don't know about any plastic bearings though. Also note, bearings are not a close enough fit type application, they are precise from fit to alignment. The tiniest thing being off when your in the thousandths of an inch tolerance range and you get binding issues. I would try the axles without the magnets and see what you get, if no binding then your good. It could be a mix of issues with the magnet, metal bearings, and binding.
