| In scroller mechanics, a high degree of surface-to-surface
contact avoids rubbing friction between parts.
As it rolls, all surfaces scroll in the same direction
at exactly the same surface speed. Scroller wheel
defies friction by avoiding the very sources of friction,
vibration and wear. Scroller technology offers cool,
smooth lube-free rotary motion.

In conventional mechanics,
parts rub and thus need to be lubricated. Scroller-
Mechanics seems to defy friction by eliminating
the very source of friction using a new yet
simple geometry.

The key to this geometry involves its high degree of
surface-to-surface contact. Over half of each roller
is wrapped (along the row) by scrolling retaining belts.
The belts move smoothly over and around the rollers
at the exact same speed as the surfaces of the rollers
(no relative surface motion).
The high rolling contact of rollers and belts virtually
eliminates the vibration, friction and wear inherent
in ordinary rolling mechanics. This contact results
in a smooth, lube-free, slip-free movement.
Belts simply pick up and lay down on the rollers; therefore,
there is no slipping, sliding, or rubbing between parts,
merely rolling friction remains. Rolling friction can
be made extremely small, depending on the accuracy of
construction and the belt tension required. (Link:

| Note: The estimated annual cost
of energy and material losses due to friction and
wear is more than $100 billion in the United
States.
Worldwide, nearly a third of the energy produced
is spent to overcome friction.
Even small reductions in friction could save
billions of dollars |
