The transmission of power on the sprocket must balance the reduced number of teeth with an important polygonal effect when using teeth smaller than 14T and the smoothness of the chain. The work of the development team in the laboratory has made it possible to optimize the shape of the tooth to reduce friction and choose stainless steel as the optimal solution between stiffness and reduction of friction.

COGNEX makes it possible to reduce the power loss of the transmission by 3% with the same chain and ratio.
