The NM Coupling, also known as the Normex Coupling, is ingeniously designed as a cylindrical pin crafted from high-quality non-metallic materials. This precision-engineered pin is strategically positioned between the two sides of the coupling and the inner surface of the outer ring, effectively enabling the transfer of torque through the column pin to seamlessly connect two half couplings. The NM flexible shaft coupling features highly durable sliders made from top-grade bakelite cloth or polyurethane. It is perfectly suited for applications requiring high speeds, large torque, and conditions with no sharp impacts between the connections.
