Normex NM Coupling
The Normex NM coupling comprises two hubs and a flexible ring designed to compensate different types of shaft misalignments. NM couplings are known for their reliability and are used in a range of applications for light, medium and heavy duty power transmission. The flexible rings are made using synthetic rubber possess high internal damping characteristic enable them to absorb and dampen torsional vibrations. Nitile rubber (NBR) is also resistant to oil, dirt, grease, moisture, ozone, and many chemical solvents making them suitable for a wide range of applications. They operate efficiently within a temperature range of -40 °C to +100 °C.
The NM Coupling can be used in any rotational direction and installation position. Our clients appreciate it for its strong connection, resistance to corrosion, lightweight design, and cost-effectiveness. We offer it in different sizes and round shapes, tailored to our client's needs. Each coupling is thoroughly tested to ensure there are no defects before it is delivered. Moreover, we provide this product at very affordable prices.
