Overview
The Do series features a unique ring-shaped output shaft consisting of a large diameter ring and a center bore installed in an extremely thin housing. An automatic assembly and processing system can be easily designed by installing the peripheral equipment inside the center bore. The diameter of the turret is oversized for the diameter of the cam, for use in applications with multiple index stops.
