Green Technology

A New Paradigm for Mechanisms

Precise Motion Technology

21Geo's Precise Motion Technology comprises a new paradigm for mechanisms on a par with gears, cams, and linkages -- yet offers more design freedom.  



Precise Motion Technology

Low Friction and Maximum Flexibility

21Geo's Precise Motion Technology coordinates the motion of components in a mechanism.  Decide for yourself how you want your components to move and the technology gives you a bearing to support that motion.
