Uneven Thrust Loads on Needle Roller Bearings

[Madison]

I know you're all perched at the edge of your seats awaiting the solution that was found for this problem.

In the end, we lucked out and found a widely available surplus mechanism that was used to rotate satellite dishes into alignment. At ~6 lbs., they're heavier than one might like, but they're substantial enough to take this load without a problem and include gearing to slow down the rotation to a manageable speed.

While I typically like to design from scratch, this was a clean solution to a sticky problem that freed up our resources to tackle some other pressing issues.

Thanks for everyone's suggestions and help.
