Flange Coupling by Rathi: Strong and Reliable Power Transmission Solution

Introduction

In industrial machinery, reliable power transmission is essential for smooth and efficient operations. Rathi flange couplings are widely used as strong and durable solutions for connecting rotating shafts, ensuring stable performance in heavy-duty applications.

What is a Flange Coupling?

A flange coupling is a type of rigid coupling that connects two shafts using flanges mounted at their ends. These flanges are joined together with bolts and nuts to transmit torque and motion efficiently. It is one of the most commonly used coupling types in industrial systems due to its simple and strong construction. (Rathi Couplings)
