What maintenance consideration is crucial for flexible couplings?

For flexible couplings, the most crucial maintenance consideration is correcting shaft misalignment. Flexible couplings are designed to accommodate some degree of misalignment between the connected shafts, typically due to factors like thermal expansion or installation inaccuracies. However, if the misalignment exceeds the coupling's design limits, it can lead to increased wear, vibration, and ultimately, failure of both the coupling and connected machinery.

It's important to regularly check and adjust the alignment of shafts to ensure optimal performance of the coupling and to extend its operational life. Proper alignment helps distribute load evenly across the coupling, minimizes stress, and reduces the likelihood of overheating and damage to adjacent components. Thus, maintaining proper alignment is essential for efficient operation and longevity of the machinery connected by flexible couplings.
