K,
We don't know what will actually happen to a Nylon or
Phenolic ball when it hits the asphalt at 60 mph. Perhaps it would
self-destruct - perhaps it would only roll.
Point is, it only has to work once to prevent damage to
the airplane. If it does get damaged, it's simple and cheap to replace the
ball...
I kinda like the idea of a rollerblade with several
rollers contacting the runway at the same time....

Hi Jack,
I've used these rollers in the glass industry for
longer than I care to admit
to. The reason they work nicely in an
industrial application is because they
don't have to spin real fast
(generally) and the surface of the ball stays
relatively nice and shiny
allowing the bearings that it seats in to do their
job. I'm afraid
that with a nylon ball after its initial contact with any
runway surface its
exterior will be damaged so quickly that it won't be able
to "float" on its
bearings, and it will soon turn into another "hockey puck".
