Couplings are essential components in mechanical power transmission systems, enabling the connection of two rotating shafts to transfer torque while compensating for misalignment, vibration, and shock. Without couplings, machines would face increased wear, vibration, and premature failure. Selecting the right coupling can enhance system efficiency, extend equipment life, and reduce downtime. Among the top names in the industry, Rathi Couplings stands out for its high-quality, performance-driven products that meet the most demanding industrial applications.

What Are Couplings?

Couplings are mechanical devices used to connect two shafts for the purpose of transmitting power. They can be rigid or flexible depending on the type of alignment and torque transmission required. Couplings also play a key role in isolating vibration, absorbing shocks, and protecting mechanical components.

Industries across the globe rely on various types of couplings for seamless operation of motors, pumps, compressors, conveyors, and other rotating machinery. With the right coupling solution from Rathi Couplings, businesses benefit from greater operational stability, safety, and performance.
