If you look at a cut-away of a ball transfer, you'll see that it's basically a large ball supported by many smaller balls. This is what makes the transfer a low friction omnidirectional bearing, which means, when you include the trackball, the only sizable friction generated is between the larger ba...

I just received the bearings today, and after some very rudimentary tests with sub-optimal placement/angling of the units, I have to say they are incredibly smooth! By far the smoothest trackball I've used with little resistance in any direction, so much so that not very much finger pressure is requ...

This project was originally started here: http://geekhack.org/index.php?topic=59444.0 Here are the goals: -Use three low friction ball transfer units/bearings to support the main trackball. Alwayse has shipped me six 11-MI-05-17 units to test*. These units are made out of stainless steal and aluminu...
