In terms of performance, Sankyo's roller gear does for rotary motions what the ball screw does for linear motions. The roller gear cam mechanism consists of a roller gear and globoidal cam. Similar to the preloading structure of a ball screw, the roller gear has no backlash, and transfers power by rolling contact for strong rigidity and excellent efficiency. And no clamping is necessary.
