Huco nylon sleeve gear (NSG) couplers are compact and efficient units capable of transmitting a high level of torque relative to their size and weight. The couplers operate silently, are electrically isolating and maintenance free. They are marginally shock absorbent and easily installed in confined spaces. Also directly interchangeable with some other makes. This part is the hub only, a complete coupling consists of two hubs and a sleeve.
