I'm doing a roulette wheel and used the common hardware lazy susan

Pics, please. The terms "roulette wheel" and "vertical" do not
compute together. Also, lazy susans are absolutely meant to be used
horizontally, and they're not designed for high-speed spins at all.


I am looking for something either better or sealed. The wheel weighs
about ten pounds. Ideas?

For a standard style roulette wheel, you need some thrust and some
axial, so I'd consider using standard wheel bearings of tapered roller
style. http://tinyurl.com/y7rm9ldc Amazon Grease them with a
low-sticktion lithium grease to get a longer spin if necessary.
