A novel mechanism for gearing is presented that uses balls to intermediate between the input and output wheels. The balls carry out pure rolling without sliding while rolling along grooves on the surfaces of the two wheels facing each other. Inside the gear, the ball-wheel contact is the same as in all ball bearings in general while, outside, the system works the same as any gear - hence the slogan "Bearings for Gearing." The technology shows a large variety of potential advantages including very high efficiency and no back-lash as well as high contact factor and large flexibility in design. Several prototype tests have proven the concept and a large number of customer design projects show the interest from the markets.
