What Are Rigid Shaft Couplings

Rigid shaft couplings are mechanical devices used to connect two shafts together in order to transmit torque and rotational motion between them. They are designed to provide a solid and permanent connection, without any flexibility or misalignment allowance. Rigid couplings are typically used when precise shaft alignment is critical, and there is no need for any compensating or damping capabilities.

Examples of rigid couplings include flange, sleeve or muff and clamp, and:


are ideal for vertical applications with no thrust bearing in the pump


support pump shaft and impeller


allow for the axial setting of the pump impeller


Rigid Shaft Coupling Benefits

Rigid shaft couplings offer several benefits and advantages in various applications. Here are some of the key benefits of using rigid shaft couplings:

  1. Precise Power Transmission: Rigid couplings provide a direct and solid connection between shafts, ensuring accurate and efficient power transmission. They minimize power loss and allow for precise control of rotational motion.

  2. Torque Capacity: Rigid couplings have high torque capacity, making them suitable for applications that require the transmission of high levels of torque. They can handle heavy loads and provide reliable torque transfer without slippage.

  3. No Backlash: Rigid couplings have zero backlash, which means they do not allow for any angular or radial movement between the connected shafts. This is crucial in applications that require precise positioning and control, such as CNC machines and robotics.
