The Zero-Max S651715 coupling hub is a machined metal, shaft-mounted hub that connects a shaft to a Zero-Max coupling assembly, providing a rigid torque transfer interface for precise motion control in industrial power transmission systems. It is compatible with Zero-Max coupling systems (CD / ServoClass / related assemblies) and designed for keyed or clamped shaft connections. The S651715 is commonly used to replace worn hubs and restore proper shaft coupling in CNC machines, packaging equipment, conveyors, and automated production lines, with construction available in steel or alloy depending on the application.
