After doing some research and designing, we probably will not use lazy susans for the reason you said. We do however have a possible solution for the piece pictured above.

Although it will definitely not be as eloquent as Neutrio's swerve drive.

The 221 Revolution 2 Swerve module uses thrust needle roller bearings, they can be found here. That is the silver ring on your first picture.

Ya we were thinking of using lazy susans for our prototype swerve modules as well but decided not to because we were afraid of this happening.

Well to be fair, very few swerve units will be as elegant as Neutrino's :rolleyes:

Yeah, we had a lazy susan on our minibot deployer in 2011, after slamming it into the pole fifty or sixty times, it was totally shot.

Can I ask what your solution was?

No they don't... The 221 Revolution 2 Swerve Modules just have a bronze bushing to separate the steering from the drive shaft.

I think you are right, but it does look like they have some type of bearing in the picture. I emailed the company and they said it was a custom part that "houses a large bushing". Large is indeed right and I am having trouble finding one that large.
