Simon,

The worm lead angle has a huge impact on efficiency. I would really want to use a quad thread worm, but I needed some backdriving resistance, so I chose dual. A single lead was just too inefficient.

The ring gear is press fit into a steel part (TC-2002-111-005)
that the worm gear (TC-2002-111-001) is bolted to. We used liquid Nitrogen (just because it is fun to play with) to shrink the ring gear and then pressed it into the steel part.

FANUC Robotics (the company I work for) is the largest non-military customer for KAYDON. I know our sales representative personally and he gives me any standard KAYDON bearing for free. In return, KAYDON is placed as a sponsor to our team. So, to answer your question; no we do not pay one penny for the KAYDON bearings. If you decide to use the CCT and need a couple of those bearings, I can probably get you a couple.
