The Phasing Hub is a static phase adjusting coupling designed for precise rotary positioning. When in motion, the Phasing Hub operates as a rigid 1:1 shaft coupling. Phase change of the coupling and connected shafts is accomplished with the drive stopped. By manually turning the Adjusting Ring, the Phasing Hub becomes a phase changing device providing infinitly variable and stepless phase correction in either direction.

Many machines and machine elements require precise angular adjustment between operating components. The need for this adjustment results from rotational misalignment at set-up, material deviation, wear and various other scenarios. The Phasing Hub is a unique, cost effective solution for such timing challenges.
