Two Boston Gear FC25 jaw coupling hubs provide a compact, reliable power-transmission connection for shafts in industrial drives, featuring a straight jaw design and an outside diameter of about 2.5 inches (FC25 size). Each steel hub is finished with a keyway and set screws for secure mounting, and is designed to work with FC25 polyurethane inserts to cushion torque and accommodate small misalignment. Commonly used to couple motors to conveyors, pumps, and other machinery in industrial drive systems, FC25 jaw couplings offer durable torque transmission with simple maintenance.
