Title: Magnetic ball-less bearings
Post by: Zimmer on December 05, 2016, 03:20:26 PM: Has anyone ever talked about this? It seems like it would be possible to make a bearing out of super strong magnets, that way instead of balls in races, two surfaces can just float around each other. Like those magnetic trains they have in china! But in a bearing.

Yeah, what if someone powerslides. Would they slip out?

So, are my grand kinds going to be skating them?

The wheels spinning generates lots of heat and energy and will weaken the magnets. Also, magnets can become depolarized through impact. Dropping a magnet can completely kill its strength. Also, to lift a human would require a huge regular magnet, making your board extremely heavy.

Sincerely,
Big Ball Bearings
