Rolling-Mechanics can often be replaced by Scrolling-Mechanics

In Scroller-mechanics
 . . . . parts move WITH each other, rather than rub AGAINST each other 
creating a rub - free, grease - free solution.

No more tons of grease dripping into our environment every year.

Appearance  &  Function

•  The bands of the wheels can be made of several materials.

    The Sandia Government Lab used Beryl  ( Copper Beryllium ) .

The wheel has four wheels acting as one wheel
    and their appearance and their rotation 
    is of wheels in the middle of a wheel. 

As they rotate, they move on their four sides
    and go in any direction without together rotating
    because they need not together rotate as they rotate.
