[Retired Starman]

Our team used a large lazy susan bearing back in 2006. We mounted a polycarbonate plate on it around which was placed a timing belt turned by a pulley on our drive motor. We found that the lazy susan bearing did not take well to the side pressure necessary to turn the load we had on top. The metal of the bearing would open up a little, making the bearing run loose and taking the tension off the belt.

If I were using the bearing again, I think I would use a drive puck on one side with a couple of idlers on the other side to keep stress off the bearing itself.
