Engineered for the precision feedback requirements of encoder applications, Zero-Max Control-Flex couplings feature a parallel linkage system that minimizes reaction forces due to unavoidable shaft misalignments. Designed with clamp-style zero backlash hubs, they have electrically insulating flex components with low weight and inertia. The couplings consist of 2 clamp-style hubs (to be attached to the system shafts) and a center flex member. The single-flex disc version of the couplings is designed for standard torque capacity; the 2-flex disc version is for increased torque capacity and torsional stiffness. The couplings can be used in packaging, machine tool, conveying and automated assembly systems.
