Product Description

The NM Coupling, also known as the Normex Coupling, is an engineering marvel crafted from advanced non-metallic materials. This cylindrical pin is ingeniously situated between the dual sides of the coupling and the interior surface of the outer ring. It masterfully transmits torque through the column pin, enabling a seamless connection between two half couplings. The NM flexible shaft coupling, with sliders fashioned from high-grade bakelite cloth or resilient polyurethane, is perfect for applications demanding high speed and substantial torque, where sharp impacts are absent in the dual connections.

Product brand: UNIISO

Name of transmission part: Water Pump Coupling

Product Structure: This coupling is a robust assembly of two cast iron claws joined by a flexible natural rubber inner ring, ensuring durability and flexibility.

Suitable Shaft Diameter: Ranges from 7mm to 75mm, accommodating a wide variety of applications.

Suitable Motor Power: Ideally suited for motors with power up to 60hp or 45kw, making it versatile for different power needs.

Product Features:

1. The coupling boasts a maximum torque capacity of an impressive 300kgm.
2. It ensures stable operationand operates with notably low noise, enhancing the user experience.
3. This product is meticulously crafted from cast iron and utilizes precision die casting techniques, greatly reducing the risk of fractures during operation.
