The NM Coupling, also known as the Normex Coupling, is a marvel of engineering that features a cylindrical pin crafted from advanced non-metallic materials. This ingenious pin is strategically placed between the two sides of the coupling and the inner surface of the outer ring, forming an efficient device that transmits torque with precision. It exquisitely connects two half couplings, ensuring seamless power transfer. Built with a flexible shaft coupling made from either durable bakelite cloth or resilient polyurethane, it's designed to excel under high-speed and large torque conditions, all while gracefully handling connections without sharp impacts.
Product brand: UNIISO
Name of transmission part: water pump coupling
The product structure is a testament to robust engineering, comprising two cast iron claws harmoniously integrated with a natural rubber inner ring, providing unmatched durability and performance.
This coupling is adaptable to a suitable shaft diameter ranging from 7mm to 75mm, making it versatile for a wide array of applications.
Designed to accommodate motor power within 60hp or 45kw, this coupling meets the demands of various power requirements with ease.
Product features:
1. The coupling boasts a formidable maximum torque of 300kgm, ensuring robust performance under challenging conditions.
2. It offers stable operation andproduces minimal noise, creating a serene working environment.
3. Demonstrating exceptional durability, the product is crafted from high-quality cast iron through precision die casting, significantly reducing the risk of fractures during operation.
