Re: Rotation Systems

We made our own 4 point contact V grrove bearing so it could support both thrust and radial loads. It came out very nice. It was able to take considerable amount of load without binding up at all. It was something like 12 inches in diameter. The V groove was filled with steel and delrin balls (alternating). It was driven by a globe motor with a 4.8:1 sprocket and chain reduction. Picture here http://www.team696.com/blog/images/06/IMG_0143.JPG We were able to pas from 90 to the left to 90 to the right and tilt from about 15 down to 50 up.
