Flexible Couplings are a critical component in mechanical power transmission systems, designed to connect two rotating shafts while accommodating misalignments and absorbing shocks. These couplings are essential in applications where system flexibility, durability, and smooth operation are required. For industries seeking high-performance and reliable solutions, Rathi Couplings offers a wide range of flexible couplings tailored to meet modern industrial demands.
What Are Flexible Couplings?
Flexible couplings are mechanical devices used to transmit torque from one shaft to another while compensating for various types of misalignment—axial, angular, or parallel. Unlike rigid couplings, flexible couplings allow controlled movement and absorb vibrations, helping protect machinery from premature wear and operational failures.
They also help isolate components from mechanical disturbances, reduce noise, and accommodate dynamic motion, making them indispensable in industrial systems such as pumps, conveyors, compressors, blowers, and more.
Applications of Flexible Couplings
Flexible couplings are used in a broad range of industries including:
- Manufacturing and Automation
- Steel and Metal Processing
- Mining and Construction Equipment
- HVAC and Power Generation
- Marine, Chemical, and Oil & Gas Industries
Whether you're working with high-speed motors or heavy-duty industrial machines, Rathi Couplings provides coupling solutions that ensure stable performance and extended equipment life.

Flexible Couplings vs. Rigid Couplings
When choosing a coupling, understanding the difference between flexible and rigid types is important:
- Flexible Couplings are ideal when shafts are not perfectly aligned or when systems require shock absorption and vibration control.
- Rigid Couplings require precise shaft alignment and offer zero movement, making them suitable for simpler systems without dynamic loads.
Flexible couplings are typically preferred for modern industrial machinery due to their ability to handle real-world mechanical challenges.
