Slip, Slide and Rub

•  Conventional mechanics have parts,

    with very little contact that move against each other.


Grease

•  All that grease and seals and maintenance

    and yet conventional mechanics still wears and fails.

    It puts limits on how and where it can be used

    and even what materials can be used.


Precision

•  Conventional bearings are made precisely

    yet need space for grease so precise positioning / movement is impossible.


Rolamite

•  Discovered in 1967,

    the principle of over-wrapping with tension to eliminate slip has been around for years.

    What was not known was how to apply this principle to continuous rotary motion.

    Rolamite  "boxed itself in",

    making the precision of parallel box sides critical as it oscillates only.

•  We were initially working on a project

    designing a simpler bike with fewer parts and lower maintenance.


(The Locus Bike)


•  No spokes or cables was easy, no sprocket or chain was tougher,

    no grease seemed impossible .... yet that was the goal.

    When we looked at existing options, we found several problems:


Friction

•  In conventional bearings, rollers, and / or retainers rub against each other,

    causing both friction and excessive wear.

Roller Mechanics
•  Scroller mechanics doesn't rub like roller mechanics, 
    because the scrolling retaining belts move with the rollers, not against.

Rolamite
•  Scrolling rotary motion doesn't "box itself in" like the linear / oscillating Rolamite does. 
    Rolamite does share scrolling wrap and the low friction results, 
    and so is perhaps a linear subset, 
    a peek at what is now the broader, more detailed field of Scroller Mechanics.

Conclusion
•  Scroller mechanics is a new type of mechanics 
    that doesn't need grease like traditional roller mechanics. 
    A cleaner, lube-free mechanics 
    means cleaner machines, cleaner maintenance and a cleaner environment.
